BACKGROUND OF THE INVENTION

It is now well established in the scientific community thatelectromagnetic waves with varying frequencies irradiated by variousdevices may be hazardous to human health. In some cases, suchelectromagnetic waves in mega- and giga-hertz range may be the mainculprit, whereas the 60-hertz electromagnetic waves may be the mainhealth concern in other cases. It cannot be too emphasized that it isvery difficult to shield against magnetic waves of the 60-hertzelectromagnetic waves which have wavelengths amounting to thousands ofkilometers and that such 60-hertz magnetic waves are omnipresent in anycorner of the current civilization.

However, intensity of such electromagnetic waves typically decreasesinversely proportional to a square of a distance from a source of suchwaves to a target. Accordingly, potentially adverse effects from suchelectromagnetic waves may be minimized by maintaining a safe distancefrom such a source. Some electrical devices, however, are intended to beused in a close proximity to an user, where typical examples of suchdevices are hair dryers, hair curlers, electric mattresses or blankets,heating pads, earphones, headphones, mobile phones, razors,toothbrushes, and the like. However, all prior art devices have failedto provide remedies to such potential hazards. For example, variousprior art electric blankets and mattresses and their shortcomings havebeen provided in the above Application of U.S. Ser. No. 11/313,921entitled “Electromagnetically-Shielded Air Heating Systems and Methods,”and various radiative heaters and their shortcomings have beensummarized in another Application of U.S. Ser. No. 11/403,899 entitled“Electromagnetically-Shielded Radiative Heating Systems and Methods.”Various conventional speakers and their shortcomings have been itemizedin two Applications of U.S. Ser. No. 11/440,135 entitled“Electromagnetically-Shielded Speaker Systems and Methods,” now issuedas U.S. Pat. No. 7,940,950, and Ser. No. 12/318,538 entitled“Electromagnetically-Countered Speaker Systems and Methods,” now issuedas U.S. Pat. No. 8,041,048, while various conventional electricactuators and their shortcomings have been described in the co-pendingapplication of U.S. Ser. No. 12,318,539 entitled“Electromagnetically-Countered Actuator Systems and Methods,” now issuedas U.S. Pat. No. 8,148,872.

Therefore, there is an urgent need for a generic counter unit capable ofbeing incorporated to various prior art devices and converting suchdevices into electromagnetically-countered systems for minimizingirradiation of the harmful electromagnetic waves therefrom. There alsois a need to provide a feasible solution for countering the harmfulwaves irradiated by various waves sources of different shapes and/orsizes. There further is a need to provide another feasible solution forcountering such harmful waves defining wavefronts of variouscharacteristics.

Another related objective of thisinvention is to arrange the counter unit to manipulate the amplitudes ofthe counter waves in various mechanisms similar to those formanipulating the directions thereof.

Another objective of the present invention is to provide an EMC systemwith at least one of the above counter units and to supply the electriccurrent or voltage thereto for countering such harmful waves by suchcounter waves emitted thereby. Accordingly, a related objective of thisinvention is to provide the counter unit with the electric current orvoltage which is supplied to the above base unit or at least one ofmultiple base units. Another related objective of this invention is toprovide the counter unit with at least a portion but not an entireportion of the electric current or voltage supplied to such a base unitor at least one of multiple base units. Another related objective ofthis invention is to provide the counter unit with such a portion of thecurrent or voltage of which the amplitudes and/or direction are modifiedbefore being supplied thereto. In all of these examples, the current orvoltage supplied to the counter unit is automatically synchronized withsuch current or voltage supplied to the base unit or at least one ofmultiple base units.

It is to be understood in all of such objectives that the counter unitsare preferably arranged to not adversely affect other intendedoperations of the systems. For example, the counter units of the EMCspeaker systems may effectively counter the harmful waves irradiated bytheir sound generating base units but may not adversely affect thequality of acoustic sounds generated thereby. In another example, thecounter units of the EMC actuator systems may effectively counter suchharmful waves irradiated by their electromotive base units but may notadversely affect the amplitude of electromotive force generated thereby.In another example, the counter units of the EMC heating systems mayalso effectively counter the harmful waves irradiated by their heatingbase units but may neither adversely affect the amount of thermal energygenerated thereby. In another example, the counter units of the EMCtransformer systems may effectively counter the harmful waves irradiatedby their transforming coils but may not adversely affect voltage levelsobtained thereby. It is also appreciated in all of such objectives thatthe counter units are preferably arranged to emit the counter waveswhich define the phase angles at least partially opposite to those ofthe harmful waves for such countering but that the counter units mayalso emit the counter waves which define the phase angles at leastpartially similar to those of the harmful waves when disposed on anopposite side of the base unit with respect to the target space or whenthe system includes multiple counter units and it is desirable to modifythe radii of curvature of the wavefronts of the counter waves. It isfurther appreciated that the electric and/or magnetic shields disclosedin the co-pending Applications may be incorporated into any of the aboveEMC systems either alone or in combination with the above counter unitsfor maximally countering the harmful waves.

The basic principle of the counter units of the genericelectromagnetically-countered systems of this invention is to emit thecounter waves which form the wavefronts similar (or identical) to thoseof the harmful waves but define the phase angles at least partiallyopposite to those of such harmful waves. Therefore, by propagating suchcounter waves to the target space, the counter waves can effectivelycounter the harmful waves in the target space by, e.g., canceling atleast a portion of such harmful waves therein and/or suppressing theharmful waves from propagating theretoward. To this end, the counterunits are arranged to emit the counter waves which define the wavefrontsmatching those of the harmful waves by various mechanisms. In oneexample, such counter units are shaped similar (or identical) to thebase units of the waves sources, or arranged similar (or identical) tosuch base units and, therefore, emit the counter waves which can counterthe harmful waves in the target space. In another example, such counterunits are disposed along one or more of the wavefronts of the harmfulwaves and emit the counter waves which are similar (or identical) to theharmful waves and, accordingly, counter the harmful waves in the targetspace. In these two examples, the counter units are to emit the counterwaves with the wavefronts which are similar (or identical) to the shapesof such counter units themselves, and such counter waves are to definethe phase angles which are at least partially opposite to the phaseangles of the harmful waves. In another example, the counter units areshaped differently from the base units, but are rather disposed in anarrangement in which the counter waves emitted therefrom may match suchharmful waves in the target space. In another example, the counter unitsare disposed across different wavefronts of the harmful waves but are toemit the counter waves which are similar (or identical) to the harmfulwaves and, therefore, counter the harmful waves in the target space. Inthe last two examples, the counter units may be arranged to emit thecounter waves with the wavefronts may or may not be similar (oridentical) to the shapes of the counter units themselves, while thecounter waves are to define the phase angles which are at leastpartially opposite to those of the harmful waves.

The basic principle of the counter units of the genericelectromagnetically-countered system of this invention may beimplemented into various prior art devices for minimizing irradiation ofthe harmful waves therefrom. For example, the counter units may beimplemented to any base units of electrically conductive wires, coils,and/or sheets or, in the alternative, into any electricallysemiconductive and/or insulative wires, coils, and/or sheets forminimizing the irradiation of the harmful waves by countering suchharmful waves by the counter waves, e.g., by canceling at least aportion of the harmful waves in the target space and/or suppressing theharmful waves from propagating toward the target space, where thecounter units may be made of and/or include at least one electricallyconductive, insulative or semiconductive material. The counter units maybe implemented into any of such base units which define the shapes whichmay be formed by incorporating one or multiple wires, coils, and/orsheets, by modifying the shapes of one or multiple wires, coils, and/orsheets, where a few examples of the modified shapes may include asolenoid and toroid each formed by modifying the shape of such a coil.Therefore and in one example, such counter units may be implemented intovarious speakers such as cone-drive speakers, electrostatic speakers,and piezoelectric speakers for minimizing the irradiation of the harmfulwaves. Accordingly, any prior art devices including theelectromagnetically-countered speakers such as earphones, headphones,wired phones, mobile phones, and audiovisual devices may be convertedinto the electromagnetically countered systems. Similarly, the counterunits may be implemented into various microphones which are inverseexamples of such speakers, and any prior art devices including suchelectromagnetically-countered microphones such as wired phones, mobilephones, audio and/or audiovisual sound systems, and an assembly of theearphone and microphone may be converted into the electromagneticallycountered systems. In another example, such counter units may beimplemented into various motors such as DC motors, universal motors, ACsynchronous motors, AC induction motors, linear motors, and the like,for minimizing the irradiation of such harmful waves. Therefore, anyprior art actuator devices including the electromagnetically-counteredmotors such as kitchen appliances (e.g., a food processor, a mixer, ajuicer, a grinder, a blender, a squeezer, a can opener, a dish washer, arefrigerator, a freezer, a cooler, and so on), cooking appliances (e.g.,an electric grill, an electric oven, an electric stove, an electricrange, an electric toaster, an electric fan for such, and the like),household appliances (e.g., a cloth washer, a cloth dryer, an airconditioner, a garage opener, a dry or wet vacuum cleaner, and so on),tools (e.g., an electric drill, an electric saw, an electricscrewdriver, an electric nail or staple gun, an electric sander, and thelike), and personal hygiene devices (e.g., an electric razor, anelectric toothbrush, an electric hair dryer, and the like) may beconverted into the electromagnetically countered systems. Similarly, thecounter units may also be implemented to various generators, and anyprior art generating devices with the electromagnetically-counteredgenerators such as AC generators, DC generators, and (automobile)alternators may also be converted into the electromagnetically counteredsystems. In another example, such counter units may be implemented intovarious transformers which include therein at least two coils, and anyprior art devices including the electromagnetically-counteredtransformers such as step-up transformers, step-down transformers, andAC/DC adaptors of various electric devices may be converted into theelectromagnetically countered systems. In another example, such counterunits may be implemented to various heating unit including at least oneresistive heating wire, heating strip, heating sheet, and/or heatingcoil for minimizing the irradiation of the harmful waves during heating.Accordingly, any prior art heating devices such as personal heatingappliances (e.g., an electric mattress or mat, an electric blanket, anelectric heating pad, and so on), cooking appliances (e.g., an electricgrill, an electric oven, an electric stove, an electric range, anelectric toaster, an electric toaster oven, and the like), and/orbeauty-related appliances (e.g., a hair dryer, a hair setter, a haircurler, a hair steamer, and the like), may be converted into theelectromagnetically countered systems. In another example, such counterunits may be implemented into various light emitting units forminimizing the irradiation of such harmful waves during lighting.Accordingly, any prior art display devices such as a cathode ray tube, alight emitting device, an organic light emitting device, an inorganiclight emitting device, and a plasma display panel may be converted intothe electromagnetically countered systems.

More product-by-process claims may be constructed by modifying theforegoing preambles of the apparatus and/or method claims and byappending thereonto such bodies of the apparatus and/or method claims.In addition, such process claims may include one or more of the abovefeatures of the apparatus and/or method claims of the present invention.

As used herein, the term “units” collectively refers to both of a “baseunit” and a “counter unit” of an electromagnetically-countered system ofthis invention, where such a system is abbreviated as the “EMC system”or simply as the “system” hereinafter. Such a classification between the“units” is primarily based upon their intended functions. That is, the“base unit” represents various parts of the EMC system which are toperform intended functions of the system such as, e.g., generatingaudible sounds from source signals (speakers and devices including such)or vice versa (microphones and devices including such), generatingelectromotive force by converting electric energy (electric motors anddevices including such) or vice versa (generators), producing visibleimages from source signals (display elements such as a CRT, LED, OLED,and PDP, and devices including such), generating heat from electricenergy (straight or coiled heating elements and devices including such),and the like. All of such “base units” irradiate the harmful waves whileperforming their intended functions, and these “base units” are alwaysincorporated in the above devices. In contrary, the “counter unit”represents those parts of the EMC system which are to perform counteringfunctions such as, e.g., canceling at least a portion of the harmfulwaves in the target space and/or suppressing or preventing the portionof such harmful waves from propagating toward the target space. Whendesirable, the “counter unit” may also be arranged to perform thefunctions intended for the “base unit” and, accordingly, serve as anextra “base unit” which also performs the countering function. Thisunit, however, is to be deemed as the “counter unit” within the scope ofthis invention unless otherwise specified. Within the scope of thisinvention, the “base unit” is therefore omnipresent in any prior artdevices, while the “counter unit” is neither physically not functionallypresent in the prior art devices.

The “base unit” is to be distinguished from a “wave source” within thescope of this invention. More particularly, the “wave source”collectively refers to portions of the EMC system irradiating suchharmful waves, whereas the “base unit” specifically refers only to theportions of the “wave source” which are directly responsible forirradiating the harmful waves and/or affecting propagation paths of suchwaves. For example, a speaker of a mobile phone is the “wave source” andthe “base units” of such a phone includes a voice coil and a permanentmagnet, where a cone and a bracket coupling to such a coil and magnetare portions of the “wave source” but not portions of the “base unit”because the cone and/or bracket neither generate the harmful waves noraffect the propagation paths thereof. Similarly, a motor of an actuatingdevice is the “wave source,” while the “base units” of the motor arepermanent magnets and/or electromagnets incorporated to a rotor and/or astator of the motor, where a shaft and a case of the motor are portionsof the “wave source” but not portions of the “base units” because theshaft and/or case neither generate the harmful waves not affect thepropagation paths thereof. Similarly, a heater of a heating device isthe “wave source” and the “base unit” of the heating device is astraight or coiled heating element, where an insulative support and anexternal coating are portions of the “wave source” but not portions ofthe “base unit” because the support and/or coating neither generate suchharmful waves nor affect their propagation paths. Accordingly, a shapeof the “wave source” is generally different from a shape of the “baseunit,” where the “base unit” may have the shape simpler or more complexthan that of the “wave source.” However, the “base unit” may be deemedas a subset of the “wave source” and, therefore, such a “base unit”almost always defines a size which is smaller than or at most equal tothat of the “wave source.”

As used herein, the term “configuration” collectively refers a shape,size, and/or arrangement, while the term “disposition” collectivelyincludes orientation, alignment, and/or distance. Accordingly, the“configuration” of the (counter or base) unit may refer to the shape ofthe unit, the size of the unit, and/or arrangement of the unit withrespect to the other of the base and counter units. Similarly, the“disposition” of the unit may refer to the orientation and/or alignmentof such a unit with respect to the other of the base and counter units,to the target space, to a direction of propagation of the harmful orcounter waves, to a direction of the electric current flowing in orvoltage applied across such a unit or the other of the base and counterunits, and the like. The “disposition” of the unit may also refer to thedistance to the other of the base and counter units therefrom, to thetarget space, and the like. When the system includes multiple counterunits, the “disposition” thereof may include the distance between atleast two of such counter units.

Within the scope of the present invention, the term “wire” collectivelyrefers to an article with a shape of a wire, a fiber, a filament, a rod,and/or a strand, and shapes of any other similarly elongated articleseach of which may be straight or curved (i.e., curvilinear), and each ofwhich may be formed into a loop, a coil, a roll, a spiral, a mesh, andthe like. The term “strip” collectively refers to an article with ashape of a strip, a bar, a pad, and/or a tape, and shapes of any otherplanar or curved articles with large aspect ratios (i.e., ratios oflengths to widths or heights), each of which may be arranged straight orcurved, each of which may be arranged in a two- or three-dimensionalconfiguration, each of which may be arranged into a loop, a coil, aroll, a spiral, a mesh, and the like. In addition, the term “sheet”collectively refers to an article with a shape of a sheet, a slab, afoil, a film, a plate, and/or a layer, and shapes of any other articleswhich are wider than the “strip,” each of which may be planar (i.e.,two-dimensional or 2-D) or curved (i.e., three-dimensional or 3-D), eachof which may be formed in a segment, a roll, and the like. The term“tube” collectively refers to an article which may define any of theshapes described hereinabove and to be described hereinafter and formingat least one lumen therethrough. Such a “tube” may be arranged straightor curved, may be arranged into a loop, a coil, a roll, a spiral, amesh, and the like. The term “coil” collectively refers to an articledefining a shape of a helix and/or a spring, and shapes of any otherarticles winding around an object along a longitudinal or short axis ofsuch an object at a constant distance from the object, and the like. The“coil” may be arranged straight or curved, may also be arranged into aloop (such as a toroid), a coil, a roll, a spiral, a mesh, and the like.The term “spiral” collectively refers to an article defining a shape ofanother helix and/or spring which may, however, expand or shrink alongthe longitudinal or short axis of an object, and shapes of any otherarticles winding around such an object at varying distances, and thelike. It is appreciated that a planar “spiral” may be formed on a singlecurvilinear plane which is normal to the longitudinal or short axis ofthe object. The term “mesh” collectively refers to an article with ashape a mesh, a net, a screen, a quilt, a fabric, and/or a garment, andshapes of any other articles which may be formed into a networkingstructure, a woven structure, an interwoven structure, and the like. Theterm “bundle” collectively refers to an article defining a shape of twoor more of the same or different elongated shapes which are aligned sideby side or laterally in such a manner that a cross-section of the“bundle” or a “bundled article” may include at least two of such shapestherein. The term “braid” collectively refers to an article with a shapeof two or more of the same of different elongated shapes which arebraided in such a manner that the “braid” or a “braided article” mayconsist of at least two of such shapes in a cross-section normal to alongitudinal and/or short axis thereof, where examples of such articlesmay include, but not be limited to, a thread, a yarn, any other articlesmade by prior art braiding techniques, and the like. It is to beunderstood that at least a portion of each of such articles formedaccording to the above terms in this paragraph may be arranged to besolid, hollow or porous such as, e.g., a foam, a sponge, and the like.It is also appreciated that each of such articles formed according tothe foregoing terms of this paragraph may be arranged to include (ordefine) at least one hole, gap or opening.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention relates to an electromagnetically-countered systemincluding at least one wave source irradiating harmful electromagneticwaves and at least one counter unit emitting counter electromagneticwaves for countering the harmful waves by the counter waves, e.g., bycanceling at least a portion of the harmful waves by the counter waves,by suppressing the harmful waves from propagating to a target space, andthe like. More particularly, the present invention relates to genericcounter units of the electromagnetically-countered systems and tovarious mechanisms for countering the harmful waves which are irradiatedfrom various base units of the wave sources by the counter units.Accordingly, the counter unit may be shaped, sized, and/or arranged tomatch its configuration with configuration of the base unit of the wavesource, thereby emitting such counter waves which automatically matchcharacteristics of such harmful waves. In the alternative, the counterunit may be shaped, sized, and/or disposed in an arrangement which isdefined along one or more wavefronts of the harmful waves, therebyemitting the counter waves which automatically match characteristics ofthe harmful waves. The present invention also relates to various counterunits which are provided as analogs of the base unit of the wave source,where the analog may approximate the base unit which is more complexthan such a counter unit, where the three- or two-dimensional base unitmay also be approximated as the two- or one-dimensional analog, and thelike. The present invention also relates to multiple simple counterunits which are simpler than the base unit but disposed in anarrangement approximating such a shape and/or arrangement of the baseunit. The present invention also relates to the counter unit which maybe shaped and/or sized according to the configuration of the base unitand disposition thereof. In addition, the present invention relates tovarious countering modes where a single counter unit may counter asingle base unit, at least two but not all of multiple base units or allof multiple base units, where multiple counter units may counter asingle base unit, more base units or less multiple units, and the like.The present invention then relates to various electric and/or magneticshields which may be used alone or in conjunction with the counter unitsto minimize irradiation of the harmful waves from the system.

The present invention also relates to various methods of countering theharmful waves by the counter waves by such source matching or wavematching. More particularly, the present invention relates to variousmethods forming the counter unit as an analog of the base unit and thenemitting the counter waves matching such harmful waves, various methodsof approximating the base unit by the simpler counter unit for thecountering and various methods of approximating the base unit bymultiple simpler counter units. The present invention also relates tovarious methods of disposing the counter unit along the wavefronts ofthe harmful waves and then emitting the counter waves for automaticallymatching such wavefronts of the harmful waves, various methods ofdisposing multiple counter units along the wavefronts of the harmfulwaves and then emitting the counter waves by the counter units forautomatically matching such wavefronts, and the like. In addition, thepresent invention relates to various methods of manipulating thewavefronts of the counter waves by disposing the counter unit closer toand/or farther away from the target space with respect to the base unit,various methods of controlling radii of curvature of the wavefronts ofthe counter waves by incorporating one or multiple counter unitsemitting such counter waves of the same or opposite phase angles,various methods of adjusting the wavefronts of the counter waves bydisposing one or multiple counter units defining the shapes similar toor different from the shapes of the base units, and the like. Thepresent invention also relates to various methods of countering theharmful waves from one or multiple base units with the counter wavesemitted by the single or multiple counter units. Accordingly, thepresent invention relates to various methods of emitting such counterwaves from a single counter unit for the harmful waves irradiated by oneor more base units, various methods of emitting such counter waves bytwo or more counter units for the harmful waves irradiated by a singleor multiple base units, and the like. In addition, the present inventionrelates to various methods of minimizing irradiation of such harmfulwaves by incorporating such electric shields, by incorporating themagnetic shields, by incorporating one or both of such shields inconjunction with the above counter units, and the like.

The present invention further relates to various processes for providingvarious counter units and various systems incorporating one or multiplecounter units therein. More particularly, the present invention relatesto various processes for forming the counter units to emit the counterwaves having the wavefronts similar to (or different from) such shapesof the counter units, various processes for forming the counter units asthe above analogs of the base units, various processes for providing thecounter units emitting such counter waves which define the similar oropposite phase angles, various processes for providing such counterunits with the wavefronts shaped similar to the harmful waves, variousprocesses for disposing the counter units in a preset arrangement andemitting therefrom the counter waves which have the wavefronts similarto such an arrangement, and the like. The present invention also relatesto various processes for assigning the single counter unit to counterthe harmful waves irradiated by the single base unit for a localcountering or to counter such harmful waves from multiple base units fora global countering, various processes for assigning multiple counterunits to counter the harmful waves irradiated by the single base unitfor the global countering or to counter the harmful waves from multiplebase units for the local or global countering depending on numbers ofthe counter and base units. The present invention further relates tovarious processes for incorporating the electric and/or magnetic shieldsfor minimizing the irradiation of such harmful waves, and variousprocesses for minimizing the irradiation of such harmful waves byemploying such shields as well as the above counter units.

The basic principle of the counter units of the genericelectromagnetically-countered systems of this invention is to emit thecounter waves which form the wavefronts similar (or identical) to thoseof the harmful waves but define the phase angles at least partiallyopposite to those of such harmful waves. Therefore, by propagating suchcounter waves to the target space, the counter waves can effectivelycounter the harmful waves in the target space by, e.g., canceling atleast a portion of such harmful waves therein and/or suppressing theharmful waves from propagating theretoward. To this end, the counterunits are arranged to emit the counter waves which define the wavefrontsmatching those of the harmful waves by various mechanisms. In oneexample, such counter units are shaped similar (or identical) to thebase units of the waves sources, or arranged similar (or identical) tosuch base units and, therefore, emit the counter waves which can counterthe harmful waves in the target space. In another example, such counterunits are disposed along one or more of the wavefronts of the harmfulwaves and emit the counter waves which are similar (or identical) to theharmful waves and, accordingly, counter the harmful waves in the targetspace. In these two examples, the counter units are to emit the counterwaves with the wavefronts which are similar (or identical) to the shapesof such counter units themselves, and such counter waves are to definethe phase angles which are at least partially opposite to the phaseangles of the harmful waves. In another example, the counter units areshaped differently from the base units, but are rather disposed in anarrangement in which the counter waves emitted therefrom may match suchharmful waves in the target space. In another example, the counter unitsare disposed across different wavefronts of the harmful waves but are toemit the counter waves which are similar (or identical) to the harmfulwaves and, therefore, counter the harmful waves in the target space. Inthe last two examples, the counter units may be arranged to emit thecounter waves with the wavefronts may or may not be similar (oridentical) to the shapes of the counter units themselves, while thecounter waves are to define the phase angles which are at leastpartially opposite to those of the harmful waves.

The basic principle of the counter units of the genericelectromagnetically-countered system of this invention may beimplemented into various prior art devices for minimizing irradiation ofthe harmful waves therefrom. For example, the counter units may beimplemented to any base units of electrically conductive wires, coils,and/or sheets or, in the alternative, into any electricallysemiconductive and/or insulative wires, coils, and/or sheets forminimizing the irradiation of the harmful waves by countering suchharmful waves by the counter waves, e.g., by canceling at least aportion of the harmful waves in the target space and/or suppressing theharmful waves from propagating toward the target space, where thecounter units may be made of and/or include at least one electricallyconductive, insulative or semiconductive material. The counter units maybe implemented into any of such base units which define the shapes whichmay be formed by incorporating one or multiple wires, coils, and/orsheets, by modifying the shapes of one or multiple wires, coils, and/orsheets, where a few examples of the modified shapes may include asolenoid and toroid each formed by modifying the shape of such a coil.Therefore and in one example, such counter units may be implemented intovarious speakers such as cone-drive speakers, electrostatic speakers,and piezoelectric speakers for minimizing the irradiation of the harmfulwaves. Accordingly, any prior art devices including theelectromagnetically-countered speakers such as earphones, headphones,wired phones, mobile phones, and audiovisual devices may be convertedinto the electromagnetically countered systems. Similarly, the counterunits may be implemented into various microphones which are inverseexamples of such speakers, and any prior art devices including suchelectromagnetically-countered microphones such as wired phones, mobilephones, audio and/or audiovisual sound systems, and an assembly of theearphone and microphone may be converted into the electromagneticallycountered systems. In another example, such counter units may beimplemented into various motors such as DC motors, universal motors, ACsynchronous motors, AC induction motors, linear motors, and the like,for minimizing the irradiation of such harmful waves. Therefore, anyprior art actuator devices including the electromagnetically-counteredmotors such as kitchen appliances (e.g., a food processor, a mixer, ajuicer, a grinder, a blender, a squeezer, a can opener, a dish washer, arefrigerator, a freezer, a cooler, and so on), cooking appliances (e.g.,an electric grill, an electric oven, an electric stove, an electricrange, an electric toaster, an electric fan for such, and the like),household appliances (e.g., a cloth washer, a cloth dryer, an airconditioner, a garage opener, a dry or wet vacuum cleaner, and so on),tools (e.g., an electric drill, an electric saw, an electricscrewdriver, an electric nail or staple gun, an electric sander, and thelike), and personal hygiene devices (e.g., an electric razor, anelectric toothbrush, an electric hair dryer, and the like) may beconverted into the electromagnetically countered systems. Similarly, thecounter units may also be implemented to various generators, and anyprior art generating devices with the electromagnetically-counteredgenerators such as AC generators, DC generators, and (automobile)alternators may also be converted into the electromagnetically counteredsystems. In another example, such counter units may be implemented intovarious transformers which include therein at least two coils, and anyprior art devices including the electromagnetically-counteredtransformers such as step-up transformers, step-down transformers, andAC/DC adaptors of various electric devices may be converted into theelectromagnetically countered systems. In another example, such counterunits may be implemented to various heating unit including at least oneresistive heating wire, heating strip, heating sheet, and/or heatingcoil for minimizing the irradiation of the harmful waves during heating.Accordingly, any prior art heating devices such as personal heatingappliances (e.g., an electric mattress or mat, an electric blanket, anelectric heating pad, and so on), cooking appliances (e.g., an electricgrill, an electric oven, an electric stove, an electric range, anelectric toaster, an electric toaster oven, and the like), and/orbeauty-related appliances (e.g., a hair dryer, a hair setter, a haircurler, a hair steamer, and the like), may be converted into theelectromagnetically countered systems. In another example, such counterunits may be implemented into various light emitting units forminimizing the irradiation of such harmful waves during lighting.Accordingly, any prior art display devices such as a cathode ray tube, alight emitting device, an organic light emitting device, an inorganiclight emitting device, and a plasma display panel may be converted intothe electromagnetically countered systems.

It is to be understood that various counter units of such genericelectromagnetically-countered systems (to be abbreviated as “EMCsystems” or simply “systems” hereinafter) of this invention may beincorporated to any electrical and/or electronic devices each of whichmay have at least one base unit and, accordingly, may irradiate theharmful waves including electric waves (to be abbreviated as “EWs”hereinafter) and magnetic waves (to be abbreviated as “MWs” hereinafter)having frequencies of about 50 to 60 Hz and/or other EWs and MWs ofhigher frequencies. It is also appreciated that the generic EMC systemsof this invention may also be incorporated into any portable orstationary electric and/or electronic devices which include at least onebase unit detailed examples of which have been provided heretofore andwill be provided hereinafter. It is further appreciated that suchcounter units may be provided in a micron-scale and incorporated tosemiconductor chips and circuits such as LSI and VLSI devices and thatsuch counter units may be provided in a nano-scale and incorporated intovarious nano devices including at least one base unit which in this casemay be a single molecule or a compound or may be a cluster of multiplemolecules or compounds.

Various aspects and/or embodiments of various systems, methods, and/orprocesses of this invention will now be described more particularly withreference to the accompanying drawings and text, where such aspectsand/or embodiments thereof only represent different forms. Such systems,methods, and/or processes of this invention, however, may also beembodied in many other different forms and, accordingly, should not belimited to such aspects and/or embodiments which are set forth herein.Rather, various exemplary aspects and/or embodiments described hereinare provided so that this disclosure will be thorough and complete, andfully convey the scope of the present invention to one of ordinary skillin the relevant art.

Unless otherwise specified, it is to be understood that various members,units, elements, and parts of various systems of the present inventionare not typically drawn to scales and/or proportions for ease ofillustration. It is also to be understood that such members, units,elements, and/or parts of various systems of this invention designatedby the same numerals may typically represent the same, similar, and/orfunctionally equivalent members, units, elements, and/or parts thereof,respectively.

In a generic aspect of this invention, an EMC system includes at leastone wave source and at least one counter unit and counters harmfulelectromagnetic waves (to be abbreviated as the “harmful waves”hereinafter) which are irradiated from the wave source with counterelectromagnetic waves (to be abbreviated as the “counter waves”hereinafter) which are emitted from the counter units. The wave sourcealways includes at least one base unit which is the real source of suchharmful waves, i.e., irradiating the harmful waves, affectingpropagation paths of the harmful waves while maintaining or alteringtheir amplitudes and/or phase angles, and so on, where examples of sucha base unit may include, but not be limited to, a conductive orsemiconductive article such as a wire, a strip, a plate, a ring thereof,a coil thereof, a spiral thereof, and a mesh thereof all of which emitsuch harmful waves when electric current flows therein, an insulativearticle such as a wire, a strip, a plate, a ring thereof, a coilthereof, a spiral thereof, and a mesh thereof all of which can not carrysuch electric current but emit the harmful waves when electric voltageis applied thereacross, a permanent magnet which can affect thedirection, paths, and/or amplitudes of such harmful waves, and the like.The wave source further includes at least one optional part whichmechanically supports or retains such a base unit but which neitherirradiates nor affects the propagation paths of the harmful waves, whereexamples of the optional part may include, but not be limited to, a caseenclosing the base unit, a protective cover, a coupler, any parts inwhich such current does not flow, any parts across which the voltage isnot applied, and the like. The counter unit is arranged to emit suchcounter waves capable of countering the counter waves, e.g., bycanceling the harmful waves and/or by suppressing the harmful waves frompropagating along a specific direction. The counter unit may be arrangedto counter the harmful waves in every direction from the base unit ofthe wave source, e.g., above, below and around such a base unit.However, such an embodiment may be costly to implement, may not befeasible, and may not be necessary, particularly when the EMC system isto be used in a specific orientation by an user who is to be protectedfrom such harmful waves. In such a case, the counter is arranged tocounter the harmful waves only around a specific target space (or area)which is generally defined between the base unit and the user (or aspecific body part thereof).

In order for the counter waves to counter (i.e., cancel and/or suppress)such harmful waves, there are a few prerequisite which the counter wavesmust satisfy. The first is the phase angles of the counter waves. Ingeneral, such counter waves preferably define the phase angles which areat least partially or substantially opposite to those of the harmfulwaves so that the counter waves may cancel and/or suppress the harmfulwaves when propagated to the target space from the same side as the baseunit. In the alternative, the counter waves may have the phase angleswhich are at least partially similar (or identical) to those of theharmful waves so that such counter waves cancel and/or suppress theharmful waves when propagated to the target space from an opposite sideof the base unit. When the system includes multiple counter units, eachcounter unit may emit the counter waves having the same, similar ordifferent phase angles. The next is the amplitudes of the counter waves.In contrary to the phase angles, such counter waves may define variousamplitudes which, however, effectively counter the harmful waves in thetarget space. When disposed closer to the target space than the baseunit, the counter unit has only to emit the counter waves with theamplitudes less than those of the harmful waves. By the same token, thecounter unit disposed farther from the base unit has to emit the counterwaves with the amplitudes greater than those of the harmful waves, whilethe counter unit disposed flush with the base unit with respect to thetarget space has to emit the counter waves with the similar or sameamplitudes as the harmful waves. When the system includes multiplecounter units, all of such counter units may be disposed at similardistances from the base unit and/or target space or, alternatively, atleast two of the counter units may be disposed at different distancesfrom the base unit and/or target space. In addition to the distancesand/or dispositions thereof, such counter waves may have variousintensities depending upon whether the counter waves counter the harmfulwaves throughout an entire portion of the target space or only at presetpositions inside such a target space. For example, the counter unitpreferably emits the counter waves which are capable of countering theharmful waves throughout the target space as the user may be situatedanywhere across the target space. When the user is to be situated onlyin preset positions of the target space, however, the counter may beshaped, sized, arranged, and then disposed to emit the counter waveswhich best counter the harmful waves in such positions but not with suchan efficiency in other parts of the target space.

Once the counter unit is arranged to emit the counter waves definingproper phase angles and amplitudes, such a counter unit may be shaped,sized, arranged, and disposed in order to counter the harmful wavesdepending on detailed countering mechanisms.

In one example, the counter unit may be shaped, sized, and/or arrangedsimilar (or identical) to the base unit, which is to be referred to as a“source matching” hereinafter. The basic concept of the “sourcematching” is that the counter unit may emit the counter waves definingwavefronts similar to a configuration (i.e., a shape, a size, and anarrangement) of the counter unit and that such wavefronts of the counterwaves automatically match wavefronts of the harmful waves, and thecounter waves counter the harmful waves due to the similarity betweenthe configurations of the counter and base units. When the systemincludes multiple base units, the single counter unit may then bearranged to emit the counter waves capable of countering the harmfulwaves irradiated by one of such base units or countering a sum of theharmful waves irradiated by at least two or all of such base units. Whenthe system includes multiple counter units, such counter units may emitthe counter waves capable of countering the harmful waves emitted by thesingle base unit or multiple base units. When the system includesmultiple counter and base units, such counter waves from each counterunit may counter the harmful waves by each base unit, a sum of suchcounter waves from at least two counter units may counter the harmfulwaves from one of the base units, the counter waves from a singlecounter unit may counter a sum the harmful waves from at least two baseunits, a sum of the counter waves from all of such counter units maythen counter a sum of the harmful waves from all of the base units, andthe like. It is preferred in this “source matching” that the counterunit emit the counter waves with the wavefronts of the configurationsimilar to that of the counter unit. It is, however, possible that sucha counter unit emits the counter waves with the wavefronts with theconfiguration different from that of the counter unit, that thewavefronts of a sum of the counter waves emitted by multiple counterunits may have the configuration different from the configuration ofeach counter unit or the arrangement of the counter units, and the like,as long as the counter waves may counter the harmful waves in such atarget space.

In another example, the counter unit may be disposed (i.e., oriented,aligned, and/or positioned) in such a manner that at least one wavefrontof the counter waves may match at least one wavefront of the harmfulwaves, where such a mechanism will be referred to as a “wave matching”hereinafter. The basic concept of the “wave matching” lies in the thatthe counter waves may counter the harmful waves when the counter unit isdisposed in such a position to match the wavefronts of such counterwaves with the wavefronts of the harmful waves as far as theconfiguration of the counter unit may be properly adjusted to satisfysuch “wave matching.” When the system includes multiple base units, asingle counter unit may be arranged to emit the counter waves capable ofmatching and countering the harmful waves irradiated by one of the baseunits or, alternatively, matching and countering a sum of the harmfulwaves irradiated by at least two or all of the base units. When such asystem includes multiple counter units, the counter units may emit thecounter waves capable of countering the harmful waves emitted by asingle base unit or multiple base units. When the system includesmultiple counter and base units, such counter waves from each counterunit may counter the harmful waves by each base unit, a sum of thecounter waves emitted by at least two counter units may counter theharmful waves from one of the base units, the counter waves from asingle counter unit may counter a sum the harmful waves from at leasttwo base units, a sum of the counter waves from all of such counterunits may counter a sum of the harmful waves irradiated by all of thebase units, and the like, as long as at least one of the wavefronts ofthe counter waves may match at least one of the wavefronts of theharmful waves in the target space.

Various counter units constructed based on the source matching and/orwave matching are to be disclosed hereinafter. It is appreciated in thesource matching that there does not exist any one-to-one correlationsbetween the configuration of such a counter unit and the configurationof the counter waves emitted thereby. That is, the counter waves ofcertain configuration (or wave characteristics) may be obtained by asingle counter unit which defines a certain shape and size and isprovided in a certain arrangement, by another counter unit which definesa similar shape and size but is provided in another arrangement, byanother counter unit which has a different shape and size but isprovided in a similar arrangement, by at least two counter unitsdefining preset shapes and sizes and provided in a preset arrangement,by the same number of counter units defining different shapes and/orsizes or in a different arrangement, by a different number of counterunits defining similar shapes and/or sizes or in a similar arrangement.It is similarly appreciated in the above wave matching that there doesnot exist an one-to-one correlation between the disposition of thecounter unit and the wavefronts of the counter waves emitted by thecounter unit. In other words, the wavefronts with certain shapes may beobtained by a single counter unit which defines a certain configurationand is disposed in a certain position with respect to the base unitand/or target space, by another single counter unit which forms anotherconfiguration and which is disposed in another position, by at least twocounter units which have preset configurations and are disposed inpreset positions, by the same number of counter units defining differentconfigurations and disposed in different positions, by a differentnumber of counter units which define different configurations and whichare disposed in different positions, and the like. It is, accordingly,appreciated that such counter units may be embodied in many otherdifferent forms and should not be limited to the following aspectsand/or their embodiments which are to be set forth herein. Rather,various exemplary aspects and/or embodiments described herein areprovided so that this disclosure will be thorough and complete, andfully convey the scope of the present invention to one of ordinary skillin the relevant art.

In another aspect of the present invention, a single generic counterunit may be provided for a single generic base unit to counter theharmful waves from the base unit by the counter waves from the counterunit. FIGS. 1A to 1F show top schematic views of exemplaryelectromagnetic countering mechanisms in each of which a single counterunit emits the counter waves capable of countering the harmful waveswhich are irradiated from a single base unit of a single wave sourceaccording to the present invention, where the base unit is a pointsource in FIGS. 1A to 1C and 1F, while the base unit is an elongatedsource in FIGS. 1D and 1E. It is appreciated that these figures,however, may also be interpreted in different perspectives. For example,such figures may be interpreted as the top cross-sectional views, wherethe base units of FIGS. 1A to 1C and 1F are wires extendingperpendicular to the sheet, and the base units of FIGS. 1D and 1E arestrips or rectangular rods also extending normal to the sheet. Inanother example, the figures may be interpreted as sectional views ofmore complex articles, where the base units of FIGS. 1A to 1C and 1F maycorrespond to sections of coils, spirals, meshes, and the like, whilethe base units of FIGS. 1D and 1E may similarly correspond to sectionsof curvilinear rods or strips. It is also appreciated in these figuresthat such base units are enclosed in the wave sources which may be casesor other parts of such a system which do not irradiate such harmfulwaves. It is further appreciated in all of these figures that the EMCsystems are disposed in such a way that the target space is formed tothe right side of the counter and base units.

In one exemplary embodiment of such an aspect of the invention and asdescribed in FIG. 1A, an EMC system 5 includes a single rectangular wavesource 10 and a single counter unit 40, where the source 10 includestherein a single base unit 10B defining a shape of a point source. Thecounter unit 40 is similarly shaped as another point source and disposedto the right side of the base unit 10B. In this arrangement, the counterunit 40 emits the counter waves of which wavefronts are identical tothose of the harmful waves irradiated by the base unit 10B. Because thecounter unit 40 is disposed closer to a hypothetical target space on theright side of the figure, such counter wavefronts always define radii ofcurvature smaller than those of the harmful wavefronts. Accordingly, thecounter unit 40 may counter (i.e., cancel or suppress) the harmful wavesonly along a line connecting the counter and base units 40, 10B or inits vicinity. It is appreciated that such an embodiment corresponds tothe source matching which turns out to be ineffective due to adiscrepancy in the radii of curvature of the wavefronts of the counterand harmful waves.

In another exemplary embodiment of this aspect of the invention and asdepicted in FIG. 1B, an EMC system 5 includes a single counter unit 40and a single rectangular wave source 10 with a single base unit 10Bdisposed therein. The base unit 10B is similar to that of FIG. 1A,however, the counter unit 40 is elongated, oriented vertically along itslength, and disposed on the right side of the base unit 10B. Due to itselongated shape, the counter unit 40 emits the counter waves whosewavefronts are also elongated vertically and, therefore, define theradii of curvature which are greater than those of FIG. 1A and whichmatch those of the harmful waves. Accordingly, such a counter unit 40defines a target space 50 across which the counter waves counter theharmful waves to a preset extent. It is to be understood that such anembodiment corresponds to the wave matching mechanism in that thecounter unit 40 is shaped similar to one of the harmful wavefronts.

In another exemplary embodiment of this aspect of the invention and asdepicted in FIG. 10, an EMC system 5 includes a single counter unit 40and a single rectangular wave source 10 with a single base unit 10Bdisposed therein. The base unit 10B is similar to that of FIG. 1A,however, the counter unit 40 is shaped and sized to conform to onewavefront of such harmful waves. That is, the counter unit 40 is shapedas an arc and disposed in an orientation concave to the right side ofthe figure or to the target space 50. Because of its arcuate shape, sucha counter unit 40 emits the counter waves of which wavefronts are alsoarcuate and, therefore, define the radii of curvature which are similaror identical to those of the harmful waves. Therefore, the counter unit40 defines a target space 50 across which the counter waves counter theharmful waves to a preset extent. It is appreciated that such anembodiment corresponds to another wave matching mechanism and that thecounter waves emitted form this arcuate counter unit 40 better matchsuch harmful wavefronts and define the target space 50 which expandsover a wider angle around the base unit 10B than those of FIGS. 1A and1B.

In another exemplary embodiment of this aspect of the invention and asdepicted in FIG. 1D, an EMC system 5 includes a single counter unit 40and a single rectangular wave source 10 with a single base unit 10B.Contrary to those of the above, this base unit 10B is rectangular andoriented vertically along its length or its long axis, and irradiatesthe harmful waves of which wavefronts define vertical and relativelystraight portions which are attributed to the length or long axis of thebase unit 10B. The counter unit 40 is shaped and sized similar oridentical to the base unit 10B, and disposed in the same orientation asthe base unit 10B. This orientation may be viewed to dispose the counterunit 40 along the vertical straight portions of the wavefronts of theharmful waves. The counter unit 40 also emits the counter waves whosewavefronts define vertical and relatively straight portions, similarlydue to the length or long axis thereof. Because such portions of thecounter wavefronts match those of the harmful wavefronts, the counterunit 40 forms the target space 40 to the right side. This embodimentcorresponds to the source matching, wave matching or their combination.It is to be understood that the counter unit of FIG. 1A is shaped andsized as the base unit but ineffective due to a discrepancy in the radiiof curvature between the wavefronts of the counter and source waves. Thecounter unit 40 of this embodiment is similarly shaped and sized as thebase unit 10B but efficiently counter such harmful waves in the targetspace 50. The primary reason of this countering lies in the fact thatboth of the harmful and counter waves define along their wavefronts thevertical straight portions which generally do not depend upon the radiiof curvature thereof. Otherwise, configuring the counter unit 40 similarto the base unit 10B and then disposing such a counter unit 10 betweenthe base unit 10B and target space generally do not provide an efficientcountering, where further details of this front arrangement are to beprovided below. It is appreciated that such an embodiment corresponds tothe source matching in which the counter unit 40 is shaped, sized,and/or arranged similar (or identical) to the base unit 10B.

In another exemplary embodiment of this aspect of the invention and asdepicted in FIG. 1E, an EMC system 5 includes a single counter unit 40and a single rectangular wave source 10 with a single base unit 10Bwhich is similar to that shown in FIG. 1D. The counter unit 40, however,is shaped and sized to conform to one wavefront of such harmful waves.Similar to that of FIG. 10, the counter unit 40 is shaped as an arc anddisposed in an orientation concave to the right side of the figure ortarget space 50. Because of its arcuate shape, such a counter unit 40emits such counter waves of which wavefronts are also arcuate and,therefore, define the radii of curvature which are similar or identicalto those of the harmful waves, not only along their vertical straightportions but also along their curved portions, mainly due to the arcuateshape of the counter unit 40. Accordingly, such a counter unit 40defines a target space 50 which also expands over a wide angletherearound and across which the counter waves effectively counter suchharmful waves. It is to be understood that this embodiment correspondsto another wave matching mechanism.

In another exemplary embodiment of this aspect of the invention and asdepicted in FIG. 1F, an EMC system 5 includes a single counter unit 40and a single rectangular wave source 10 which has a single base unit 10Btherein. Both of the counter and base units 40, 10B are identical tothose of FIG. 1A. However, the counter unit 40 is disposed on anopposite side of a target space 50 with respect to the base unit 10B andaligned with the base unit 10B as are the cases with the precedingfigures. In this arrangement, the counter unit 40 emits the counterwaves of which wavefronts are identical to those of the harmful wavesirradiated by the base unit 10B. Because the counter unit 40 is disposedfarther away from the target space 50, such counter wavefronts definethe radii of curvature which approach and then match those of theharmful wavefronts when disposed at a proper distance from the base unit10B. Accordingly, the counter unit 40 disposed in this rear arrangementmay effectively counter the harmful waves and defines the target space50 expanding over a wide angle around the base unit 10B. It isappreciated that the sole difference between the counter units of FIGS.1A and 1F is their dispositions, i.e., one disposed in the “frontarrangement” of FIG. 1A and another disposed in the “rear arrangement”of FIG. 1F. It is also appreciated that the rear arrangement is notnecessarily superior to the front arrangement and that further detailsof selecting the proper arrangement are to be provided below. It isfurther appreciated that this embodiment corresponds to the wavematching in which the counter unit 40 is disposed at the position formatching the harmful wavefronts with the counter wavefronts.

Although not included in the figures, a single counter unit may bedisposed in an arrangement flush with the base unit with respect to thetarget space, flush with a direction of propagation of the harmfulwaves, flush with another direction along which electric current flowsin the base or counter unit, flush with another direction in whichelectric voltage is applied across the base or counter units, and so on.In this “lateral” arrangement, the radii of curvature of the counterwavefronts automatically match those of the harmful wavefronts and,therefore, the counter waves effectively match and then counter theharmful waves in the target space. For this arrangement, however, thewave source has to provide a space in which the counter unit may beincorporated. Therefore, the counter unit may be implemented inside thewave source and close to the base unit thereof when applicable.Otherwise, the counter unit may instead be disposed over, below orbeside the wave source and as close to the base unit as possible. It isappreciated, however, that the counter unit disposed next to the baseunit may propagate the counter waves onto the base unit and obstructnormal operation of the base unit. Accordingly, the lateral arrangementis preferably selected only when such an arrangement may not obstructthe normal operation of the base unit, wave source including such or EMCsystem including such. When the lateral arrangement does not affect theoperation of the base unit but the counter unit may not be disposedclose to the base unit due to space limitations, two or more counterunits may be disposed on opposing sides (e.g., left and right, top andbottom, front and rear, and the like) of such a base unit and as closeto the base unit as possible. Such counter units may also be arranged toemit the counter waves a sum of which may be symmetric or skewed towarda preset direction based on the wave characteristics of the harmfulwaves.

In another aspect of the present invention, multiple generic counterunit may be provided for a single generic base unit for countering theharmful waves irradiated by the base unit with the counter waves emittedby all of such counter units or emitted by at least two but not all ofsuch counter units. FIGS. 2A to 2F are top schematic views of exemplaryelectromagnetic countering mechanisms in each of which multiple counterunits emit counter waves to counter harmful waves irradiated from asingle base unit of a single wave source according to the presentinvention, where the base unit is a point source in FIGS. 2A to 2E,while the base unit is an elongated source in FIG. 2F. It is appreciatedthat these figures, however, may also be interpreted in differentperspectives. For example, such figures may be viewed as the topcross-sectional views, where the base units of FIGS. 2A to 2E are wiresextending perpendicular to the sheet, and the base unit of FIG. 2F is astrip or a rectangular rod also extending normal to the sheet. Inanother example, the figures may be interpreted as sectional views ofmore complex articles, where the base units of FIGS. 2A to 2E maycorrespond to sections of coils, spirals, meshes, and the like, whereasthe base unit of FIG. 2F may similarly correspond to sections ofcurvilinear rods or strips. It is also appreciated in these figures thatsuch base units are enclosed in the wave sources which may be cases orother parts of such a system which do not irradiate such harmful waves.It is further appreciated in all of these figures that the EMC systemsare disposed in such a way that the target space is formed to the rightside of the counter and base units.

In one exemplary embodiment of such an aspect of the invention and asdescribed in FIG. 2A, an EMC system 5 includes two counter units 40 anda single wave source 10 including a single base unit 10B. The base unit10B is similar to those of FIGS. 1A to 1C, while a pair of counter units40 are disposed between the base Ni 10B and a target space 50. Suchcounter units 40 are also disposed symmetric to the base unit 10B andflush with each other with respect thereto, i.e., the counter units 40are disposed at an equal distance from the base unit 10B and/or targetspace 50. Such counter units 40 are arranged to emit the counter wavesof the same phase angles so that the wavefronts of the counter wavesfrom each counter unit 40 are superposed onto each other whileincreasing their amplitudes. As the counter waves propagate, theirwavefronts which correspond to a sum of each set of wavefronts from eachcounter unit 40 increase their radii of curvature as if they are emittedby the elongated counter units of FIGS. 1B to 1E. Therefore, the counterwavefronts match the harmful wavefronts, and the pair of counter units40 match and counter the base unit 10B while defining the target space50 expanding over a limited angle therearound. It is to be understoodthat disposing two or more counter units 40 result in flattening thewavefronts of the counter waves and increasing the radii of curvature ofthe superposed portions of the counter wavefronts. It is furtherappreciated that this arrangement corresponds to the wave matching inwhich multiple counter units 40 are disposed along one wavefront of theharmful waves.

In another exemplary embodiment of this aspect of the invention and asdepicted in FIG. 2B, an EMC system 5 includes three counter units 40 anda single wave source 10 enclosing therein a single base unit 10B. Thebase unit 10B is similar to those of FIGS. 1A to 1C, while the counterunits 40 are similar to those of FIG. 2A such that all counter units 40are disposed between the base unit 10B and target space 50 and flushwith the base unit 10B. However, the system 5 includes one more counterunit 40 so that an array of three counter units 40 approximate thewavefronts of such harmful waves better than those of FIG. 2A.Accordingly, the counter units 40 emit the counter waves which bettercounter the base unit 10B and define the target space 50 expanding overa wider angle therearound than those of FIG. 2A. It is appreciated thatdisposing three counter units 40 result in further flattening thesuperposed wavefronts of the counter waves and also result in increasingthe radii of curvature of such portions of the wavefronts of the counterwaves. It is also appreciated that this arrangement is another wavematching where all three counter units 40 are disposed along onewavefront of the harmful waves.

In another exemplary embodiment of this aspect of the invention and asdepicted in FIG. 2C, an EMC system 5 includes two counter units 40 and asingle wave source 10 including a single base unit 10B which is similarto those of FIGS. 1A to 1C. Two counter units 40 are disposed onopposite sides of the base unit 10B at an equal distance therefrom andalso flush with the base unit 10B with respect to a target space 50.Similar to those of all of the preceding embodiments, such counter units40 emit the counter waves defining the similar or identical phase anglesso that the counter waves emitted by each of such counter units 40superpose onto each other for not only increasing their amplitudes butalso flattening the superposed portions of their wavefronts whileincreasing the radii of curvature of such wavefronts. Accordingly, thecounter units 40 counter the harmful waves and define the target space50 spanning around a rather limited angle therearound. It is appreciatedthat this arrangement is rather the source matching than the wavematching in that the counter units 40 are disposed in the symmetricarrangement and effect the elongated counter unit arranged flush withthe base unit 10B.

In another exemplary embodiment of this aspect of the invention and asdepicted in FIG. 2D, an EMC system 5 includes three counter units 40 anda single wave source 10 enclosing therein a single base unit 10B whichis similar to those of FIGS. 1A to 1F. Contrary to those of FIG. 2B,three counter units 40 are disposed on an opposite side of a targetspace 50 with respect to the base unit 10B. The counter units 40 arearranged flush with each other relative to the base unit 10B and targetspace 50 and also spaced away from each other at an equal distance.Similar to those of FIGS. 2A to 2C, both of outer counter units 40A, 40Care arranged to emit the counter waves defining the phase angles atleast partially opposite to those of the harmful waves so thatsuperposed portions of the wavefronts of the counter waves are flattenedwhile increasing their radii of curvature. Contrary to those of thepreceding figures, a middle counter unit 40B is arranged to emit thecounter waves defining the phase angles which are at least partiallysimilar to those of such harmful waves and opposite to those of thecounter waves emitted by the outer counter units 40A, 40C. Therefore, anet effect of incorporating the middle counter unit 40B is to sharpenthe curvature of the superposed portions of the wavefronts of a sum ofthe counter waves and to define the target space 50 expanding around anarrower angle around the base unit 10B, as manifest in a comparisonbetween the target spaces 50 of FIGS. 1F and 2D. That is, byincorporating multiple counter units 40A-40C emitting the counter wavesof the phase angles opposite to each other, it is feasible to preciselymanipulate the wavefronts of the sum of such counter waves and theirradii of curvature for better matching the wavefronts of the harmfulwaves. It is appreciated that such an embodiment may corresponds to thesource matching, wave matching or a combination thereof.

The counter units 40A-40C of this embodiment may be incorporated indifferent arrangements. For example, only two counter units may beincluded to emit the counter waves with opposite phase angles, whereresulting wavefronts of the sum of the counter waves are not symmetricbut skewed to one or an opposite side. In addition, the distancesbetween the counter units may be manipulated to adjust the wavefronts ofa sum of the counter waves regardless of the number of the counterunits. Moreover, the counter units emitting the counter waves definingthe phase angles similar to those of the harmful waves may be employedas the outer units to further sharpen the superposed portions of thecounter waves.

In another exemplary embodiment of this aspect of the invention and asdepicted in FIG. 2E, an EMC system 5 includes three counter units 40 anda single wave source 10 enclosing therein a single base unit 10B whichis similar to those of FIGS. 1A to 1C. The counter units 40A-40C arealso similar to those of FIG. 2B so that all of such counter units40A-40C are disposed between the base unit 10B and target space 50 andsimilar to each other, that the counter units 40A-40C emit the counterwaves of the same or similar phase angles, and so on. However, eachcounter unit 40A-40C is arranged to form an arcuate article shaped andsized to match a portion of a wavefront of the counter waves. Inaddition, both of upper and lower counter units 40A, 40C are spaced awayfrom each other and also disposed along one wavefront of the harmfulwaves, whereas a middle counter unit 40B is disposed between the upperand lower counter units 40A, 40C and along an adjacent wavefront of theharmful waves in such a manner that superposed portions of thewavefronts of a sum of the counter waves are flattened while defininglarger radii of curvature and match the wavefronts of the harmful waves,thereby forming a target space 50 which expands over a wide angle aroundthe base unit 10B. It is to be understood that this arrangement isanother wave matching where all three counter units 40A-40C are disposedalong multiple wavefront of the harmful waves.

In another exemplary embodiment of this aspect of the invention and asdepicted in FIG. 2F, an EMC system 5 includes three counter units 40 anda single wave source 10 enclosing therein a single base unit 10B. Whilethe base unit 10B is similar to those of FIGS. 1D and 1E, the counterunits 40 are similar to those of FIG. 2B and emit the counter waveswhich are flattened and define vertical straight portions therealong.Therefore, the counter waves match the vertical straight portions of theharmful waves and define a target space 50 similar to that of FIG. 1D.It is appreciated that this embodiment is another source matching inwhich three counter units 40 approximate the elongated base unit 10B.

In another aspect of the present invention, a single generic counterunit may also be provided for multiple generic base units for counteringthe harmful waves from such base units by the counter waves from thecounter unit. In one example, such a counter unit may be arranged tocounter a sum of the harmful waves irradiated by each base units, wheredetailed disposition of the counter unit may depend upon configurationsand/or dispositions of the base units, amplitudes and/or directions ofthe harmful waves irradiated by such base units, and the like. Basedthereupon, the counter unit may be disposed symmetrically to all or atleast some of the base units, may be incorporated in the front, rear orlateral arrangement, and the like, where such arrangements are generallyreferred to an “global or overall countering” hereinafter. In anotherexample, the counter unit is rather arranged to counter the harmfulwaves irradiated by only one of multiple base units, where such anarrangement is generally referred to as “local or individual countering”hereinafter. This local countering may only be effective when otheruncountered base units irradiate negligible amounts of such harmfulwaves, when other uncountered base units irradiate non-negligibleamounts of the harmful waves to other directions than the target space,and the like. Otherwise, it is preferred to manipulate the counter unitto counter the harmful waves of the uncountered base units, to includeadditional counter units for countering those harmful waves, and thelike.

It is appreciated that various countering mechanisms describedhereinabove for a single base unit may equally be applied to the systemwith multiple base units in the global countering mechanism. That is,the above countering mechanisms may be applied not to such harmful wavesirradiated by the single base unit but to a sum of the harmful wavesirradiated by multiple base units. When the system is to operate in thelocal countering mechanism, the aforementioned mechanisms may also beapplied to each of multiple base units regardless of an exact number ofsuch base units.

In another aspect of the present invention, multiple generic counterunit may also be provided for multiple generic base units for counteringthe harmful waves from such base units by the counter waves from thecounter unit. In one example, multiple counter units are provided in thesame number as the base units and each counter unit is arranged tocounter only one of such base units in the local countering mechanism.Alternatively, at least one of such counter units may counter only oneof such base units based upon the local countering mechanism, while atleast one another of the counter units may counter at least two of thebase units in the global countering mechanism. In another example, aless number of counter units are provided such that each counter unit isarranged to counter at least two of the base units based on the globalcountering mechanism, that at least one of the counter units countersone of the base units based on the local countering mechanism while atleast one another of the counter units counters at least two of the baseunits in the global countering mechanism, and the like. In anotherexample, a greater number of counter units are provided such that eachbase unit may be countered by at least two of the counter units, that atleast one of the counter units counters one of the base units in thelocal countering mechanism and at least one another of the counter unitsmay counter at least two of such base units in the global counteringmechanism, and so on. In all of these examples, any of the above front,rear or lateral countering mechanisms may be used by the counter units,where such countering mechanisms may be same or different for eachcounter unit.

Configurational and/or operational variations of such EMC systems andtheir counter units as well as configurational and/or operationalmodifications of such EMC systems and their counter units as exemplifiedin FIGS. 1A to 1F and FIGS. 2A to 2F also fall within the scope of thepresent invention.

As described above, a typical EMC system includes at least one wavesource and at least one counter unit, where the wave source in turnincludes or encloses at least one base unit therein and where thecounter unit may include at least one optional electric connector suchas a lead wire and at least one optional coupler for coupling thecounter unit to other parts of the system. The EMC system may alsoinclude at least one optional case member which encloses at least aportion of the base unit, at least a portion of the counter unit, andthe like. Alternatively, an entire portion of the counter and/or baseunits may be exposed with or without such a case member.

More specifically, the counter unit consists of various parts such as atleast one body, at least one optional support, and at least one insert.The body of the counter unit qualitatively corresponds to the base unitof the wave source in that such a body is the sole component of thecounter unit which emits the counter waves when the electric currentflows therein, when the electric voltage is applied thereacross, and thelike. Therefore, such a body may preferably be made of and/or include atleast one electric conductor when the electric current is to flowtherein, may be made of and/or include any electrically conductive,semiconductive or insulative material when the electric voltage is to beapplied thereacross, and the like. The support serves to mechanicallysupport the above body and/or retain such a body therein for mechanicalprotection and/or electrical isolation. The insert is typically used toaugment amplitudes of the counter waves, particularly when the counterunit includes at least one coil of conductive wire into which such aninsert is disposed. The insert may be made of and/or include variousmagnetic materials such as, e.g., ferromagnetic materials, paramagneticmaterials, diamagnetic materials, and ferrimagnetic materials, where theferromagnetic materials are the preferred ones. It is appreciated thatthe counter unit is generally arranged to maintain its configurationwhile emitting such counter waves, where this fixed configuration may beembodied by forming the body of the counter unit of rigid materials, byfixedly coupling the body of the counter unit to the support, and so on.In the alternative, the counter unit may be arranged to change its shapewhile emitting such counter waves, where this variable configuration maybe embodied by forming the body of the counter unit of elastic ordeformable materials, by movably coupling the body of the counter unitto the support, and the like. It is appreciated that the counter unitemitting such counter waves is to be opposed by the base unitirradiating the harmful waves of the same or similar magnetic polarity.Accordingly, such a counter unit tends to move while emitting thecounter waves and a special provision may have to be implemented when itis desirable to fix the counter unit during its operation.

The counter may be provided in various configurations which typicallyrefer to shapes, sizes, arrangements, and the like. In general, theconfiguration of the counter unit depends upon the above counteringmodes (such as the source matching and wave matching) and/or counteringmechanisms (such as the front, rear or lateral arrangement, local orglobal matching, and the like) which generally depend on theconfigurational characteristics of the base units, wave characteristicsof the harmful waves, and the like. In addition, the configuration ofthe counter unit also depends upon the shapes, sizes, orientation,and/or dispositions of the target spaces which are to be formed on oneside of the counter unit.

The shape of the counter unit may be arranged to be identical to orsimilar to the shape of the base unit, where such a counter unit is tobe constructed to emit the counter waves which match the harmful wavesautomatically. The shape of the counter unit may instead be arranged tobe different from the shape of the base unit, where such a counter unitmay be provided in other shapes, may be wound around the base unit, mayenclose at least a portion of the base unit therein, may be enclosed byat least a portion of the base unit, and the like. Such a counter unitmay define a shape of a wire, a strip, a sheet, a tube, a coil, aspiral, and/or a mesh, may define a combination of two or more of suchshapes without defining any holes or openings therethrough, may definean array of two of more of such shapes while defining multiple holesand/or openings therethrough, and the like, where examples of thecombinations and/or arrays may include, but not be limited to, a bundleincluding multiple identical or different shapes bundling each other, abraid of multiple identical or different shapes braided along eachother, and the like. The counter unit may also be made of a mixturewhich includes at least two materials and which are also provided in anyof the above shapes, combinations, and/or arrays. It is appreciated thatthe coil (including a solenoid or a toroid), the spiral, the mesh, andthe arrays thereof may be particularly useful in the wave matching aswill be described below. It is also appreciated that all of multiplecounter units may define the same shape or that at least two but not allof such counter units may define the same shape. Alternatively, all ofsuch counter units may define different shapes.

The counter unit may be shaped to conform to the base unit so that thecounter waves by the counter unit better match the harmful waves, wheresuch a counter unit may be conformed to such a base unit whileapproximating the base unit or providing further details to the baseunit. Alternatively, the counter unit may be shaped to not conform tothe base unit while manipulating the counter waves to match the harmfulwaves. This arrangement may be embodied when a single counter unitcounters multiple base units or when multiple counter units counter asingle base unit. It is appreciated in such an arrangement that thecounter unit(s) may be provided with proper electrical energy (e.g.,current or voltage) for emitting the counter waves capable of matchingand countering the harmful waves in the target space. It is alsoappreciated that all of multiple counter units may conform to the baseunit(s) or that at least two but not all of the counter units mayconform to the base unit(s). In the alternative, all of the counterunits may not conform to the base unit(s).

When one or multiple counter units are shaped similar or identical toone or multiple base units, the counter units are preferably arranged toapproximate the base units. When the base unit forms a three-dimensional(or 3-D) shape, the counter unit may be constructed as athree-dimensional analog with a similar shape or simpler shape, atwo-dimensional (or 2-D) analog or an one-dimensional (or 1-D) analog.When the base unit defines a 2-D shape, the counter unit may befabricated as a 2-D of a similar or simpler shape or 1-D analog. Whenthe base unit forms an 1-D shape, the counter unit may be provided asanother 1-D analog defining a similar or simpler shape. When a singlecounter unit has to counter multiple base units, the counter unit mayapproximate only a major base unit as one of such analogs, mayapproximate at least two of such base units into one of the analogs, andthe like. When multiple counter units counter a single base unit, eachcounter unit may approximate only a portion of the base unit. Whenmultiple counter units are to counter multiple counter units, thecounter units may approximate the base units into the analogs of thesame dimension or into various analogs provided in different dimensions.It is appreciated that those analogs conform to the base units and,accordingly, that the analogs may define rather straight or curvedshapes depending upon the shapes of the base units. It is alsoappreciated that the analogs preferably maintain similarity with thebase units, where such similarity may be maintained in terms of lengthsof such counter and base units, widths thereof, heights thereof,thicknesses thereof, diameters or radii thereof, radii of curvaturethereof, numbers of revolutions or turns thereof, ratios of suchlengths, ratios of such widths, ratios of such thicknesses or heights,ratios of such diameters or radii, ratios of such numbers, and the like.When a single base unit is countered by a single counter units, suchconfigurational parameters are defined in each of the base and counterunits. When a single counter unit counters multiple base units, suchconfigurational parameters are defined in the counter unit, in an arrayof all of such base units, in an array of at least two but not all ofsuch base units, and the like. When multiple counter units counter asingle base unit, such configurational parameters are defined in thebase unit, in an array of all of such counter units, in an array of atleast two but not all of such counter units, and the like. When multiplecounter units counter the same or different number of base units, suchconfigurational parameters are also defined individually or in arrays asdescribed above.

When the single or multiple counter units are shaped similar oridentical to the single or multiple base units, the counter units areinstead arranged to provide details to the base units, not in a sense ofadding structures not existing in the base units but in a context ofstreamlining the wavefronts of the counter waves for the better purposeof matching the wavefronts of such counter waves with those of theharmful waves. For example, one or multiple small counter units may bedisposed around (or inside) one or more major counter units formanipulating outer (or inner) edges of the wavefronts of a sum of thecounter waves emitted by the major counter units. In another example,one or multiple small counter units may also be disposed closer to (oraway from) one or more major counter units to manipulate the radii ofcurvature of the wavefronts of a sum of the counter waves which areemitted by the major counter units. Such small or minor counter unitsmay be incorporated in various relations with respect to one or moremajor counter units for other purposes as well, as far as incorporationof such minor counter units may improve matching between the counter andharmful waves in the target space. Accordingly, when the system includesmultiple counter units, all of the counter units may be arranged toapproximate the base unit(s), all of such counter units may be arrangedto provide details to the base unit(s), or some but not all of thecounter units may approximate the base unit(s).

The counter unit may be arranged to define various cross-sections alonga longitudinal or long axis thereof, its short axis which may beperpendicular or otherwise transverse to the long axis, and the like. Inone example, the counter unit is arranged to define an uniformcross-section along at least one of such axes so that the counter wavesemitted thereby also define the wavefronts defining the same shapesalong such axes. In another example, the counter unit may be constructedto change its cross-section along at least one of such axes so that thecounter waves emitted thereby also define the wavefronts varying theirshapes along at least one of such axes. When the system has multiplecounter units, all of such units may define the same shape or at leasttwo of such counter units may define different shapes.

The counter unit may be arranged to have various sizes, where such acounter unit may emit the counter waves of proper amplitudes capable ofeffectively countering the harmful waves thereby. For example, thecounter unit incorporated in the front arrangement may define a smallersize than the base unit due to its closer disposition toward the targetspace, whereas the counter unit incorporated in the rear arrangement maydefine a larger size than the base unit due to a greater distance towardthe target space. However, the size of the counter unit may bedetermined by other factors such as, e.g., the shape of the counterunit, amplitudes of electric energy (i.e., electric current and/orvoltage) supplied thereto, and the like. Therefore, the counter unit inthe front arrangement may define a larger size than the base unit whileemitting a less amount of the counter waves per an unit area, whereasthe counter unit in the rear arrangement may define a smaller size thanthe base unit while emitting a greater amount of the counter waves peran unit area, and so on. That is, the size of the counter unit may bedeemed as a secondary parameter which may be determined by other factorssuch as, e.g., the shape of the counter unit, amplitudes of the electricenergy supplied thereto, distances to the base unit and/or target space,arrangement of the counter unit(s), orientation thereof, and the like.

The counter unit may be arranged to have various sizes along itslongitudinal axis and/or short axis. In one example, the counter unit isarranged to define an uniform size along at least one of such axes sothat the counter waves emitted thereby also define the wavefrontsdefining the same shapes along such axes, assuming that the same amountof the electric energy is supplied thereto. In another example, thecounter unit may be constructed to change its size along at least one ofthe axes so that the counter waves emitted thereby also define thewavefronts varying their shapes along such axes. In addition, thecounter unit may maintain the same size along at least one of such axeswhile varying its shapes therealong. When the system includes multiplecounter units, such counter units may have the same size or at least twoof such units may define different sizes.

Multiple counter units may also be incorporated in various arrangements,where such counter units are arranged to emit the counter waves capableof automatically matching such harmful waves due to the arrangement. Inone example, such counter units may be incorporated into an arrangementwhich conform to the shape of a single base unit or conform to anotherarrangement of multiple base units such that the counter waves match theharmful waves in the target space. In another example, the counter unitsmay be incorporated in an arrangement which does not conform to theshape of the single base unit or does not conform to the arrangement ofmultiple base units. This arrangement may be embodied when multiplecounter units counter a single base unit or when multiple counter unitsare to counter a different number of multiple base units. It isappreciated in such an arrangement that the counter unit(s) may beprovided with proper electrical energy (e.g., current or voltage) foremitting the counter waves which are capable of matching and counteringthe harmful waves in the target space. The counter units may be disposedin an arrangement symmetric to the base unit and/or target space so thatthe counter waves emitted thereby also match the symmetric harmfulwaves. Conversely, the counter units may also be disposed in anarrangement which is asymmetric to the base unit or target space suchthat the asymmetric counter waves counter the asymmetric harmful wavesin the target space. The single counter unit or multiple counter unitsmay be incorporated in an arrangement which encloses therein at least aportion of one or multiple base units. Conversely, the single counterunit or multiple counter units may be incorporated in anotherarrangement in which at least a portion of such a counter unit(s) may beenclosed by one or multiple base units. It is appreciated that thearrangement generally connotes a pattern of multiple counter units butthat such an arrangement may also mean an orientation and/or alignmentof a single counter unit.

The counter may also be provided in various dispositions which generallyrefer to orientations, alignments, distances, mobilities, and the like.In general, such disposition of the counter unit depends on suchcountering modes (such as the source matching or wave matching),countering mechanisms (such as the front, rear or lateral arrangement,local or global countering, and the like), configurations of the counterunit, and the like, each of which generally depend on theconfigurational characteristics of the base units, wave characteristicsof the harmful waves, and so on. In addition, the dispositions of thecounter unit also depend upon the shapes, sizes, orientation, and/ordispositions of the target spaces defined on one side of the counterunit. It is appreciated as rules of thumb that such counter unit(s) maybe typically disposed closer to the base unit(s) in the local counteringmechanism and that the counter unit(s) may be disposed away from thebase unit(s) in the global countering mechanism.

The counter unit may be disposed in various orientations such that thecounter waves emitted thereby may be properly oriented with and countersuch harmful waves. In one example, the counter unit may be disposed inan orientation defined with respect to a direction of propagation of theharmful waves, e.g., by orienting its long axis normal to the directionof such propagation. In another example, the counter unit may bedisposed in another orientation which is defined with respect to adirection of the electric current or voltage, e.g., by orienting itslong axis parallel to, normal to or in a preset angle with respect tothe direction of the electric energy. In another example, the counterunit may instead be disposed in another orientation which is definedwith respect to the longitudinal and/or short axes of the base unit. Itis appreciated that such orientations of the counter unit typicallydepend on other configurations of the base unit, particularly when sucha base unit is arranged to irradiate the harmful waves in a directiondifferent from at least one of its axes, different from a windingdirection of its coil or other parts, and the like. When the systemincludes multiple counter units, all of such counter units may bedisposed in the same orientation, each counter unit may be disposed in adifferent orientation, at least two but not all of the counter units maybe disposed in the same orientation, and the like.

The counter unit may be disposed in various alignments such that thecounter waves emitted thereby may be properly aligned with and countersuch harmful waves. In one example, the counter unit may be aligned withone or more of the above directions and/or axes, may be wound in thesame direction as the base unit, and the like. In another example, thecounter unit may be misaligned with at least one of the above directionsand/or axes, may be wound in a direction different from that of the baseunit, and the like. When the system includes multiple counter units, allof such counter units may be aligned in the same direction and/or axis,each counter unit may be aligned in a different direction or axis, atleast two but not all of such counter units may be aligned in the samedirection or axis, and the like. When the system includes multiplecounter units, all of such counter units may be disposed in the samealignment, each counter unit may be disposed in a different alignment,at least two but not all of the counter units may be aligned in the sameorientation, and the like.

The counter unit may further be disposed in a lateral alignment, anaxial alignment, a concentric alignment, and the like. In the lateralalignment, one or multiple counter units may be disposed side by sidewith respect to the base unit or between the base units along the longand/or short axes of such base unit(s). In the axial alignment, one ormultiple counter units are disposed along a direction of one or more ofsuch axes at a preset distance(s) from such base unit(s). In theconcentric alignment, one or multiple counter units may be disposedinside the single base unit, may be surrounded with multiple base units,may enclose the single or multiple base units, and the like.

The counter unit may be disposed in various distances from the base unitand/or target space. In one example, such a counter unit may be fixedlycoupled to the system at a preset distance from its base unit so as toemit the counter waves with the wavefronts matching those of the harmfulwaves. When desirable, the counter unit may receive variable electricalenergy (i.e., current or voltage) such that the amplitudes of thecounter waves may vary according thereto in order to counter the harmfulwaves of varying amplitudes, to define different target spaces, and thelike. In another example, the counter unit may be movably coupled to thesystem and translate or rotate between two positions so as to emit thecounter waves and dispose their wavefronts in different locations withrespect to the harmful waves with or without varying the amplitudes ofthe counter waves. Therefore, the counter unit counters the harmfulwaves by the counter waves with the wavefronts of which characteristicsvary according to the position of the counter unit with respect to thebase unit and/or target space. In another example, the system mayinclude therein multiple counter units and manipulate wave emittingoperation of each of the counter units. By properly recruiting all orsome of such counter units with or without manipulating the amplitudesof the counter waves emitted therefrom, the system may counter theharmful waves while defining the target space in various locations withrespect to the base unit. When the system include multiple counterunits, all of such units may be fixedly incorporated therein, all ofsuch units may be movably incorporated therein, or at least two but notall of such units may be movable incorporated therein, and the like.

The disposition of the counter unit may be assessed in terms of thedistances measured along the longitudinal axis of the base unit, alongthe short axis thereof, around at least one of the axes, and the like.The counter unit may be disposed closer to the target space than thebase unit as in the front arrangement, farther away from the targetspace than the base unit as in the rear arrangement, flush with thetarget space as in the lateral arrangement, and the like. When thesystem includes multiple counter units, all of such units may bedisposed in the same arrangement or at least two of such units may bedisposed in different arrangements. In addition, all of the counterunits may be disposed at an equal distance from the base unit or,alternatively, at least two of such counter units may be disposed atdifferent distances therefrom. It is appreciated that the counter unitis preferably disposed on the same side of the base unit with respect tothe target space. When the counter unit is disposed on an opposite sideof the base unit with respect to the target space, however, the counterunit may still be able to counter the harmful waves, although such adisposition may not be the preferred embodiment.

The counter unit may be incorporated into various parts of the systemand disposed in various exposures as well. When the system includes thecase member, the counter unit may be disposed on or over an exteriorsurface of the case member, on or below an interior surface of the casemember, embedded into the case member, and/or inside the case member.Such a counter unit may instead be disposed on or over an exteriorsurface of the wave source, on or below an interior surface of such awave source, embedded between such surfaces of the wave source, insidethe wave source, and the like. The counter unit may also be disposed onor over an exterior surface of the base unit, on or below an interiorsurface of the base unit, embedded between such surfaces of the baseunit, inside the base unit, and the like. In addition, such a counterunit may be disposed and enclosed by at least a portion of the baseunit. Similarly, at least a portion or an entire portion of the counterunit may also be exposed through the system, through the case member,through the wave source, through the base unit, and the like. Moreover,the counter unit may fixedly or movably couple with one or more existingparts of the system, wave source, and/or base unit or, in thealternative, may be coupled thereto by a coupler. Similarly, the counterunit may be spaced away from or may form an unitary article with such asystem, wave source, and/or base unit.

The counter unit may be made of and/or include various materials inorder to emit the counter waves having proper amplitudes in response tothe electric energy supplied thereto and matching the harmful waves. Inone example, the counter and base units may be made of and/or includethe same materials so that such units may emit the same amount of thecounter and harmful waves per an unit amount of such electric energy. Inanother example, the counter and base units may include at least onecommon material and at least one different material so that such unitsmay emit the similar but not identical amount of the counter and harmfulwaves per the unit amount of the electric energy. In yet anotherexample, the counter and base units may be made of and/or includedifferent materials so that the counter and base units emit differentamounts of waves per the unit amount of the electric energy. In general,various characteristics of the counter and base units determined bytheir compositions may be electric resistance or conductivity, magneticpermittivity, resonance frequency, and the like. Thus, the counter unitmay be arranged to define the same, similar or different conductivity,permittivity, and resonance frequency based on its composition. Anentire portion of the counter unit may be arranged to have an identicalcomposition or, alternatively, various portions of the counter unit maybe arranged to have different compositions which may vary along the longor short axis thereof. When the system includes multiple counter units,all of such counter units may have the same composition, at least twobut not all of the counter units may have the same composition, or allof such counter units may have different compositions, thereby alsomaintaining or varying the above properties therealong.

As described hereinabove, precisely matching the phase angles (eitheropposite or similar) of the counter and harmful waves is a prerequisitefor countering the harmful waves irradiated from the base unit by thecounter waves emitted by the counter unit. This phase matching may beattained by supplying proper electric energy (i.e., electric current orvoltage) to such base and counter units and optionally electricallycoupling such counter and base units with each other. For illustrationpurposes, the electric energy supplied to the base unit is to bereferred to as a “source energy” hereinafter, and the electric currentand voltage of the “source energy” are to be referred to as “sourcecurrent” and “source voltage” hereinafter, respectively. In one example,identical source current or voltage may be supplied to the base andcounter units either sequentially or simultaneously so that such phaseangles of the harmful and counter waves are properly synchronized. Inanother example, the counter unit is supplied with only a portion of thesource current or voltage sequentially or simultaneously, where thephase angles of such harmful and counter waves are still synchronized aswell. In another example, the base unit is first supplied with thesource current or voltage, while the system thereafter modifies theamplitudes or directions of the source current or voltage and thensupplies the modified current or voltage to the counter unit. As long asthe phase angles of such source energy is maintained duringmodification, the counter and harmful waves are properly phasesynchronized. In another example, the base unit is supplied with thesource energy, and the system provides an analog of such source energyand supplies the analog energy to the counter unit with or withoutmodifying the amplitudes and/or directions thereof, where such a systemmay employ various electronic components, circuits, and/or controllersto provide such an analog. As long as the phase angles of the electricenergy is maintained in the analog energy, the counter and harmful wavesare phase synchronized as well. In another example, the counter unit iselectrically coupled to the base unit in a series mode, in a parallelmode or in a hybrid mode, where the counter unit is supplied with thesource energy, modified source energy or analog energy as describedabove and where the counter unit may be supplied with such energysequentially or simultaneously with the base unit. When the systemincludes multiple counter units, all of such counter units may besupplied with the same energy, at least two but not all of such unitsmay be supplied with the same energy, each unit may be supplied withdifferent energy, and the like. When the system includes multiple baseunits which are supplied with different source energies, the singlecounter unit may be supplied with only one of such energies, with acombination of at least two of such energies, and the like. When thesystem includes multiple counter units, such units may couple with thebase unit by the same or different modes, may be supplied with the sameor different energies sequentially or simultaneously, and the like. Itis appreciated in all of the above examples that the phase matching alsodepends upon other configurations and/or dispositions of the counterunit so that a direction of winding of the counter unit, orientation ofthe counter unit, and/or alignment thereof may have to be considered toaccomplish the proper phase matching.

Further details of such source and wave matching will be providedhereinafter. As described hereinabove, it has been understood in such asource matching that there does not exist any one-to-one correlationsbetween the configuration of such a counter unit and the configurationof the counter waves emitted thereby. That is, the counter waves ofcertain configuration (or wave characteristics) may be obtained by asingle counter unit which defines a certain shape and size and isprovided in a certain arrangement, by another counter unit which definesa similar shape and size but is provided in another arrangement, byanother counter unit which has a different shape and size but isprovided in a similar arrangement, by at least two counter unitsdefining preset shapes and sizes and provided in a preset arrangement,by the same number of counter units defining different shapes and/orsizes or in a different arrangement, by a different number of counterunits defining similar shapes and/or sizes or in a similar arrangement.It has also been appreciated in such a wave matching that there does notexist an one-to-one correlation between the disposition of the counterunit and the wavefronts of the counter waves emitted by the counterunit. In other words, the wavefronts with certain shapes may be obtainedby a single counter unit which defines a certain configuration and isdisposed in a certain position with respect to the base unit and/ortarget space, by another single counter unit which forms anotherconfiguration and which is disposed in another position, by at least twocounter units which have preset configurations and are disposed inpreset positions, by the same number of counter units defining differentconfigurations and disposed in different positions, by a differentnumber of counter units which define different configurations and whichare disposed in different positions, and the like. However, there are afew heuristic rules which may apply not only to the source matching butalso to the wave matching. The first rule is that the counter unitdisposed in the front arrangement preferably defines a characteristicdimension greater than that of the base unit when other things equal soas to increase the radii of curvature of the wavefronts of the counterwaves and to attain better matching between the counter and harmfulwaves. The second rule is the reverse of the first rule and dictatesthat the counter unit disposed in the rear arrangement preferably has acharacteristic dimension less than that of the base unit in order todecrease the radii of curvature of the wavefronts of the counter wavesand to attain better matching between the counter and harmful waves. Inorder to match the amplitudes of the counter and harmful waves, however,the longer or wider counter unit in the front arrangement is arranged toemit the counter waves with the amplitudes less than those of theharmful waves. Similarly, the shorter or narrower counter unit in therear arrangement is arranged to emit the counter waves defining theamplitudes greater than those of the harmful waves. The third rule isthat disposing multiple counter units emitting the counter waves of thesame or similar phase angles tends to flatten the wavefronts of a sum ofthe counter waves and to increase the radii of curvature of thewavefronts of the counter waves. The fourth rule is the reverse of thethird rule and dictates that disposing a less number of counter unitstend to sharpen such wavefronts of the sum of the counter waves and todecrease the radii of curvature of the wavefronts of the counter waves.The fifth rule is that the wavefronts of the sum of the counter wavesmay be sharpened and the radii of curvature of such wavefronts may bedecreased when at least one but not all of multiple counter units may bearranged to emit the counter waves with the phase angles opposite tothose of other counter units. It is appreciated that these rules do notgenerally apply to the counter units emitting the counter waves with thewavefronts defining the shapes different from the shape of the counterunit, and that those rules do not generally apply to the counter unitsof the non-uniform emitting power either which will be described ingreater detail below.

A main purpose of the source matching is to manipulate the configurationof the counter unit to match that of the base unit such that the counterwaves emitted from the counter unit better match the harmful wavesirradiated from the base unit. When a system preferentially depends uponthe source matching to counter the harmful waves, its counter unit maypreferably be disposed within a preset or reasonable distance from thebase unit, for any advantages which may be obtainable by the similarlyconfigured counter unit may be lost otherwise. It is to be understoodthat the source matching is most useful when the base unit has a simpleor symmetric configuration or when it is reasonable feasible toconstruct a replica of a complex base unit. When the system includes asingle wave source including multiple base units or includes multiplewaves sources each including at least one base unit, the single counterunit may be arranged to attain the source matching with multiple baseunits or multiple counter units may be arranged to perform the sourcematching with multiple base units. The source matching may include ashape matching, a size matching, an arrangement matching, a dispositionmatching, an intensity matching, and other configurational matching.

Some details of the shape matching have been disclosed heretofore. Forexample, the counter unit may be formed as a 3-D (or bulk) analog whichis a replica or an approximation of one or multiple 3-D base units, maybe provided as a 2-D (or planar) analog which is an approximation of asingle or multiple 3-D or 2-D base units or which is a replica of asingle or multiple 2-D base units, may also be formed as an 1-D (orlinear) analog which is an approximation of one or multiple 3-D, 2-D or1-D base units or which is a replica of a single or multiple 1-D baseunits, and the like. Similarly, multiple counter units may beconstructed as 3-D analogs which are the replica or approximation of oneor multiple 3-D base units, may be formed as the 2-D analogs which arethe approximation of one or multiple 3-D or 2-D base units or which arethe replica of a single or multiple 2-D base units, may be provided asthe 1-D analogs which are the approximation of a single or multiple 3-D,2-D or 1-D base units or which are the replica of one or multiple 1-Dbase units, and the like. Such analogs may have continuous shapes orshapes with multiple holes or openings, may form solid shapes ordeformable shapes, may define symmetric or asymmetric shapes, and thelike. The shapes of the analogs may also be determined by the foregoingcountering mechanisms or, conversely, such shapes may dictate theselection of other configurations of the analogs, proper counteringmechanisms adopted thereby, and the like.

The size matching may be embodied by defining the counter unit to belarger than, similar to or smaller than the base unit whether or notmaintaining the similarity between the configurations of such counterand base units. Whether or not the counter unit may emit the counterwaves which have the wavefronts of the similar shapes as the counterunit itself, the size of the counter unit determines an extent ofdispersion or flattening of the counter waves, edge characteristics ofthe wavefronts, and the like. As described hereinabove, the size of thecounter unit is also dictated by various countering mechanisms adoptedthereby, disposition thereof, amplitudes of the electrical energysupplied thereto, and the like. Conversely, the size of the counter unitmay dictate the selection of other configurations thereof, propercountering mechanisms, and the like.

The disposition matching may be embodied by manipulating the orientationof the counter unit, alignment thereof, distance to the base unit and/ortarget space therefrom, its mobility, and the like. As described herein,the counter unit may be oriented in the preset relations with respect tovarious axes and/or various directions, may be disposed in the front,rear or lateral arrangement, may be aligned or misaligned with suchdirections and/or axes, may be aligned or misaligned with the base unitaxially, radially, angularly, concentrically, laterally, and the like.The disposition of the counter unit may also be dictated by variouscountering mechanisms adopted thereby, shapes and sizes thereof,amplitudes of the electrical energy supplied thereto, and the like.Conversely, the disposition of the counter unit may dictate theselection of other configurations thereof, proper countering mechanisms,and the like.

The intensity matching may be embodied by manipulating the amplitudes ofthe counter waves emitted by the counter unit. For example, the counterwaves may define the amplitudes greater than, similar to or less thanthose of the harmful waves when measured at a certain distance from thebase unit, when measured across the target space or at a preset positionin the target space, and the like. The amplitudes of the counter wavesare further dictated by various countering mechanisms adopted thereby,shapes and sizes thereof, disposition thereof, amplitudes of suchelectrical energy supplied thereto, and the like. Conversely, theamplitudes of the counter waves may determine the selection of otherconfigurations thereof, proper countering mechanisms, and the like.

A main purpose of the wave matching is to dispose the counter unit alongat least one of such wavefronts of the harmful waves and to emit thecounter waves defining the wavefronts capable of matching and counteringthose of the harmful waves. When a system preferentially depends on thewave matching to counter the harmful waves, its counter unit may bedisposed anywhere around the base unit in any distance as long as thecounter wavefronts may match the harmful wavefronts. It is appreciatedthat the wave matching is most powerful when the base unit defines arather complex or asymmetric configuration or when it is impossible toconstruct a replica or approximation of a complex base unit. When such asystem includes a single wave source having multiple base units orincludes multiple waves sources each including at least one base unit,the single counter unit may be arranged to attain the wave matching withmultiple base units or multiple counter units may instead be arranged toperform the wave matching with multiple base units. The only onedisadvantage or complication as to the wave matching is that detailedshapes and distribution of the wavefronts of the harmful waves have tobe assessed a priori.

In one type of the wave matching, the counter waves are emitted by atleast one counter unit defining an uniform emitting capacity in whichamplitudes per an unit configuration of the counter unit such as, e.g.,its length, its width, its radius or diameter, its area, and/or itsweight is maintained to be uniform thereacross. Therefore, such acounter unit emits the counter waves having the wavefronts which aresimilarly shaped as the counter unit itself and, when disposed along thewavefront of the harmful waves, counters the counter waves whiledefining the target space. In another type of the wave matching, suchcounter waves are emitted by another counter unit with a non-uniformemitting capacity in which amplitudes per the unit configuration of thecounter unit vary thereacross. In such an arrangement, the counter unitemits the counter waves of the wavefronts which are not similar to theshape of the counter unit. Therefore, the counter unit of thisnon-uniform capacity are disposed not along a single wavefront of theharmful waves but across at least two of such wavefronts so as to emitthe counter waves capable of matching the harmful waves and defining thetarget space.

It is appreciated that the counter units with the uniform emittingcapacity may also be disposed along at least two wavefronts of theharmful waves as exemplified in FIG. 2E. When multiple counter units aredisposed in different wavefronts of the harmful waves, such units mayalso be arranged to emit the counter waves of different amplitudes inorder to compensate discrepancies in the distances to the base unittherefrom. Such compensation may be attained by various means, e.g., byadjusting the shapes and sizes of the counter units, by manipulating theamount of the electric energy supplied thereto, by controlling theorientations and/or alignments of such counter units, and the like. Asfar as a sum of the counter waves defines the wavefronts which matchthose of the harmful waves in the target space, such counter units maybe disposed along adjacent or space-apart wavefronts of the harmfulwaves in various configurations and/or dispositions.

Similar to their counterparts in the case of the source matching, thecounter unit for the wave matching may similarly define a shape of awire, a strip, a sheet, a tube, a coil, a spiral, and/or a mesh, mayalso define a combination of two or more of such shapes without definingany holes or openings therethrough, may define an array of two of moreof such shapes while defining multiple holes and/or openingstherethrough, and so on, where examples of such combinations and/orarrays may include, but not be limited to, a bundle of multipleidentical or different shapes bundling each other, a braid of multipleidentical or different shapes braided along each other, and the like.Such a counter unit may then be disposed along the single or multiplewavefronts of the harmful waves.

The EMC systems of the present invention are specifically intended tocounter various harmful waves in a carrier frequency range or anextremely low frequency range from about 50 Hz to about 60 Hz or anotherfrequency range of less than about 300 Hz. Therefore, in the preferredembodiment of this invention, various counter units of the EMC systemsare arranged to emit the counter waves in the carrier frequency range orextremely low frequency range of from about 50 Hz to about 60 Hz oranother frequency range of less than about 30 Hz, thereby effectivelycountering the harmful waves in the comparable frequency ranges.Considering various medical findings and/or presumptions that a mainculprit of the EM waves are those in these frequency ranges, thesecounter units are believed to effectively eliminate those harmfulfrequency components from the harmful waves irradiated from the baseunits of various electric and electronic devices.

Although not preferred, various counter units of the EMC systems of thepresent invention may also be arranged to emit the counter waves in anultra low frequency range of less than about 3 kHz, the counter waves ina very low frequency range of less than about 30 kHz, and the counterwaves in a low frequency range of less than about 300 kHz for counteringthose harmful waves in the same or similar frequency ranges. The counterunits may also be arranged emit the counter waves in other frequencyranges such as, e.g., the radio waves of frequencies which range fromabout 5×10² Hz to about 10⁸ Hz, microwaves of frequencies which rangefrom about 10⁸ Hz to about 10¹² Hz, and so on, in order to counter theharmful waves of similar frequency ranges. When desirable, the counterunits may also be arranged to emit the counter waves defining higherfrequencies such as, e.g., ultraviolet rays of frequencies ranging fromabout 7.5×10¹⁴ Hz to about 10¹⁷ Hz, X-rays of frequencies ranging fromabout 7×10¹⁶ Hz to about 10¹⁹ Hz, gamma rays in a frequency range beyond5×10¹⁸ Hz, and the like, for countering the harmful waves of similarfrequency ranges.

Such counter units may further be arranged to selectively counterspecific components of the harmful waves or, alternatively, tospecifically preserve specific components of such harmful waves whilecountering (i.e., canceling and/or suppressing) the rest of the harmfulwaves. For example and particularly when the harmful waves includehigher frequency components, the counter units may be specificallyarranged to preserve beneficial waves such as, e.g., infrared raysincluding far infrared rays in a frequency range from about 300 gHz toabout 10 tHz, medium infrared rays in a frequency range from about 10tHz to about 100 tHz, near infrared rays in a frequency range from about100 tHz to about 700 tHz, and the like, while countering the rest of theharmful waves including those of the carrier frequency range andextremely low frequency ranges. Conversely, the counter units may bearranged to emit the infrared rays including such far-, medium-, and/ornear-infrared rays as well.

In another aspect of the present invention, various counter units mayalso be implemented into the base units of various devices and convertsuch devices to the EMC systems in which the harmful device EM wavesirradiated by their base units may be countered (i.e., canceled and/orsuppressed) by the counter waves emitted by their counter units.

In one exemplary embodiment of this aspect of the present invention, thecounter units may be implemented into any base units shaped aselectrically conductive wires, strips, sheets, tubes, coils, spirals,and/or meshes or, in the alternative, to any electrically semiconductiveand/or insulative wires, strips, sheets, tubes, coils, spirals, and/ormeshes for minimizing the irradiation of the harmful waves by counteringsuch harmful waves by the counter waves, e.g., by canceling at least aportion of the harmful waves in the target space and/or suppressing theharmful waves from propagating to such a target space. Such counterunits may be made of and/or include at least one material which may thenbe electrically conductive, insulative or semiconductive. The counterunits may be implemented to any of the base units which have the shapesformed by one or multiple wires, strips, sheets, tubes, coils, spirals,and/or meshes, by modifying the shapes of one or multiple wires, strips,sheets, tubes, coils, spirals, and/or meshes, where a few examples ofthe modified shapes may be a solenoid and a toroid each formed bymodifying the shape of the coil. In general, the counter units of thisembodiment may be disposed in any of the foregoing arrangements and maycounter the harmful waves by any of the foregoing mechanisms.Accordingly, a similarly or identically shaped and/or sized counter unitmay be disposed lateral or side by side to one or more base units, maybe axially, radially or angularly aligned with one or more base units,may enclose therein one or more base units, may be enclosed by one ormore base units, may wind around one or more base units, may be wound byone or more base units, and the like, based on the source matching. Inthe alternative, a similarly or differently shaped and/or sized counterunit may be disposed along one or more wavefronts of the harmful wavesirradiated by one or more base units for the wave matching. In addition,such counter units may be employed in a proper number and/or arrangementto counter the harmful waves according to the local countering or globalcountering.

In another exemplary embodiment of this aspect of the present invention,the counter units may also be implemented into any conventional electricand/or electronic elements such as, e.g., resistors, inductors,capacitors, diodes, transistors, amplifiers, and other signal processorsand/or regulators in order to counter the harmful waves which areirradiated by the elements, where such electric and/or electronicelements function to manipulate at least one input signal suppliedthereto and to produce at least one output signal at least partiallydifferent from the input signal. All of the above electric and/orelectronic elements may qualify as the base units within the scope ofthe present invention when the unsteady current flows therein or whenthe unsteady voltage is applied thereacross. In addition, the aboveelements may also qualify as the base units within the scope of thisinvention when any of the elements produces the unsteady output signal(i.e., the electric current or voltage) in response to the input signalwhich may be steady or unsteady. Therefore, any of the above prior artelements and/or devices including such elements may be converted intothe EMC elements by incorporating thereinto various counter units havingany of the above configurations in any of the above dispositions and/orarrangements, thereby countering the harmful waves in any of the abovemechanisms. It is noted that such counter units may be provided in anydimension so that such EMC elements may be provided in a range ofmicrons or nanometers.

In another exemplary embodiment of this aspect of the invention, thecounter units may also be incorporated into various speakers to counterthe harmful waves irradiated by their base units, where examples of thespeakers may include, but not limited to, cone-drive speakers,electrostatic speakers, and piezoelectric speakers. Therefore, anyconventional devices including these EMC speakers such as earphones,headphones, wired phones, mobile phones, and audiovisual devices may beconverted into various EMC systems such as EMC earphones, EMCheadphones, EMC wired phones, EMC mobile phones, and EMC audiovisualsystems. FIGS. 3A to 3I are schematic perspective views of exemplarycounter units implemented to speakers including various base unitsaccording to the present invention, where FIGS. 3A to 3D exemplifyvarious counter units implemented into prior art cone-drive speakers andcountering their base units, while FIGS. 3E to 3I represent variouscounter units implemented into conventional piezoelectric speakers andcountering their base units. It is to be understood in FIGS. 3A to 3Dthat permanent magnets disposed around or inside speaker cones areomitted in the figures for simplicity of illustration or, in thealternative, that the cone-drive speakers are the magnetless speakersystems disclosed in the co-pending Application of U.S. Ser. No.12/318,538 entitled “Electromagnetically-Countered Speaker Systems andMethods,” now issued as U.S. Pat. No. 8,041,048. It is to be similarlyunderstood in FIGS. 3E to 3I that only piezoelectric plate andelectrodes are selected as representative base units of prior artpiezoelectric speakers. It is therefore appreciated that otherconductive, semiconductive, and/or insulative parts of such speakerswhich may emit the harmful waves are to be omitted from all of thesefigures and that, when necessary, such parts may be properly counteredby resorting to any of such counter units as described above. It is alsoappreciated in FIGS. 3A to 3I that various speakers and their counterunits are disposed in order to define the target spaces on top of eachfigures.

In one example of FIG. 3A, a cone-drive speaker 22 typically includes acone 22C and at least one voice coil 22V wound around the cone 22C. Aswell known in the art, the voice coil 22V defines dynamic magneticfields therearound when supplied with source current, and interactionbetween the dynamic magnetic fields of the voice coil 22C and staticmagnetic fields formed by permanent magnets (not included in thisfigure) vibrates the cone 22C while generating audible sounds inresponse to the source current. In order to counter the harmful wavesirradiated by the voice coil 22V (i.e., the base unit of this speaker22), at least one counter unit 40 is disposed according to a presetrelation to the voice coil 22V. In this example, the counter unit 40 isformed as another coil defining a greater radius of curvature than thevoice coil 22V. In this context, this counter unit 40 is topreferentially operate in the mode of the source matching, moreparticularly, the shape matching. In addition, the counter unit 40 isdisposed below the target space and voice coil 22V in the reararrangement so that the counter unit preferably emits such counter wavesof amplitudes greater than those of the harmful waves due to a greaterdistance to the target space than the voice coil 22V. The counter unit40 is further aligned with a longitudinal axis of the voice coil 22V sothat centers of the wavefronts of the counter waves coincide with thoseof the wavefronts of the harmful waves. In order to ensure such counterwaves to have the phase angles at least partially opposite to those ofthe harmful waves, the source current or an analog thereof may besupplied to the counter unit 40 in a direction which is identical oropposite to that of the source current flowing in the voice coil 22Vdepending on a winding direction of the wire in the counter unit 40.Accordingly, the counter unit 40 may emit the counter waves which arealigned with the harmful waves and which define the phase anglesopposite to those of such harmful waves, thereby matching and counteringthe harmful waves in the target space. As mentioned above, such acounter unit 40 may be viewed as a 3-D analog of the voice coil 22Vwhich defines the shape similar to that of the voice coil 22V but aconfiguration larger or wider than that of the voice coil 22V. Whendesirable, the counter unit 40 may be disposed at a preset distance fromthe voice coil 22V in which the wavefronts of the counter waves from thecounter unit 40 may match those of the harmful waves from the voice coil22V as have been mentioned in the wave matching. In all of theseexamples, such a speaker 22 is converted into the EMC speaker system ofthis invention by the counter unit 40.

The above counter unit 40 may be modified into other configurations, maybe implemented into other dispositions, and/or may counter the harmfulwaves in other mechanisms. For example, such a counter unit may have adifferent radius of curvature which may be smaller than that of thevoice coil, which may be constant or may change along its longitudinalaxis, and the like. In another example, the counter unit may be disposedin the front arrangement while defining a radius of curvature which maybe greater than, similar to or less than that of the voice coil. Inanother example, two or more similarly or differently shaped counterunits may be disposed in various arrangements for such local or globalcountering.

In another example of FIG. 3B, a cone-drive speaker 22 also includes acone 22C and at least one voice coil 22V wound around the cone 22C. Inorder to counter the harmful waves irradiated by the voice coil 22V, atleast one counter unit 40 is shaped similar to the voice coil 22V and isdisposed according to a preset relation to the voice coil 22V. In thisexample, this counter unit 40 is to operate based on the sourcematching, more particularly, the shape matching. In addition, thecounter unit 40 is disposed around at least a portion of the voice coil22V in the lateral and concentric arrangements so that the counter unitpreferably emits the counter waves of the amplitudes similar to orslightly less than those of the harmful waves due to a similar orslightly greater distance to the target space than the voice coil 22V.The counter unit 40 is also aligned with the longitudinal axis of thevoice coil 22V such that centers of the wavefronts of the counter wavesalign with those of the wavefronts of the harmful waves. The sourcecurrent or an analog thereof may also be supplied to the counter unit 40in a direction which is identical or opposite to that of the sourcecurrent flowing in the voice coil 22V based on a winding direction ofthe wire in the counter unit 40 in order to ensure the counter waves todefine the phase angles at least partially opposite to those of theharmful waves. Accordingly, the counter unit 40 emits the counter waveswhich are aligned with the harmful waves and define such phase anglesopposite to those of the harmful waves, thereby matching and counteringthe harmful waves in the target space. When desirable, the counter unit40 may be disposed at a preset radial or axial distance from the voicecoil 22V in which the wavefronts of the counter waves from the counterunit 40 may match those of the harmful waves from the voice coil 22V ashave been mentioned in the wave matching. In all of these examples, thespeak 22 is converted into such an EMC speaker system of this inventionby the counter unit 40. Other configurational and/or operationalcharacteristics of the counter unit 40 of FIG. 3B are similar oridentical to those of the counter unit of FIG. 3A.

The above counter unit 40 may be modified into other configurations, maybe implemented into other dispositions, and/or may counter the harmfulwaves in other mechanisms. For example, such a counter unit may have adifferent radius of curvature which may be smaller than that of thevoice coil and may be disposed inside the cone, which may be constant ormay vary along its longitudinal axis, and the like. In another example,such a counter unit may be disposed to enclose a different portion ofthe voice coil or to enclose an entire portion thereof while defining aradius of curvature greater than, similar to or less than that of thevoice coil. In another example, multiple similarly or differently shapedcounter units may be disposed in various arrangements for such local orglobal countering. It is to be understood in FIGS. 3A and 3B that thevoice coils and counter units may be replaced by each other. That is,each figure may be interpreted such that an outer coil represents thelarger voice coil and that an inner coil is a counter unit which isenclosed by the outer voice coil, where other features of FIGS. 3A and3B also apply thereto.

In another example of FIG. 3C, a cone-drive speaker 22 also includes acone 22C and at least one voice coil 22V wound around the cone 22C. Inorder to counter the harmful waves irradiated by the voice coil 22V, acounter unit 40 is made of a mesh having multiple openings therein andwrapped into an annular tube in an arrangement similar to that of thevoice coil 22V. The counter unit 40 is then disposed around at least aportion of the voice coil 22V in the lateral and concentric arrangementsso that the counter unit 40 emits the counter waves of the amplitudessimilar to or slightly less than those of the harmful waves due to asimilar or slightly greater distance to the target space than the voicecoil 22V. The counter unit 40 is further aligned with the longitudinalaxis of the voice coil 22V so that centers of the wavefronts of thecounter waves align with those of the wavefronts of such harmful waves.The source current or an analog thereof may be supplied to the counterunit 40 in a direction which ensures the counter waves to have the phaseangles at least partially opposite to those of the harmful waves.Accordingly, the counter unit 40 emits the counter waves which arealigned with the harmful waves and have the phase angles opposite tothose of the harmful waves, thereby matching and countering such harmfulwaves in the target space. When desirable, the counter unit 40 may bedisposed at a preset radial or axial distance from the voice coil 22V inwhich the wavefronts of such counter waves by the counter unit 40 maymatch those of the harmful waves from the voice coil 22V as described inthe wave matching. In all of these examples, the speak 22 is convertedinto the EMC speaker system of this invention by including the counterunit 40 therein. Other configurational and/or operationalcharacteristics of such a counter unit 40 of FIG. 3C are similar oridentical to those of the counter units of FIGS. 3A and 3B.

The above counter unit 40 may be modified into other configurations, maybe implemented into other dispositions, and/or may counter the harmfulwaves in other mechanisms. For example, such a counter unit may beformed as a solid annular tube of other shapes without any openings, anannular porous tube of other shapes, and the like. In another example,the counter unit may define a different radius of curvature which may besmaller than that of the voice coil and may be disposed in the cone,which may be constant or may vary along its longitudinal axis, and thelike. In another example, such a counter unit may be disposed to enclosea different portion of the voice coil or to enclose an entire portionthereof while having a radius of curvature greater than, similar to orless than that of the voice coil. In another example, multiple similarlyor differently shaped counter units may also be disposed in variousarrangements for such local or global countering.

In another example of FIG. 3D, a cone-drive speaker 22 also includes acone 22C and at least one voice coil 22V wound around the cone 22C. Inorder to counter the harmful waves irradiated by the voice coil 22V, acounter unit 40 is provided as a sheet of a mesh having multipleopenings therein. This counter unit 40, however, is made of a mesh whichis slightly different from that of FIG. 3C. For example, the mesh ofFIG. 3D defines multiple openings formed between concentric and radialwires of the counter unit 40, while the mesh of FIG. 3C defines multipleopenings formed between horizontal and vertical wires of its counterunit. Such a counter unit 40 is disposed over the voice coil 22V in thefront arrangement so that the counter unit 40 emits the counter waves ofamplitudes less than those of the harmful waves due to a shorterdistance to the target space than the voice coil 22V. A center of thecounter unit 40 is also aligned with the longitudinal axis of the voicecoil 22V so that centers of the wavefronts of the counter waves alignwith those of the wavefronts of the harmful waves. The source current orits analog may also be supplied to the counter unit 40 in a directionwhich ensures the counter waves to have the phase angles at leastpartially opposite to those of the harmful waves. Accordingly, thecounter unit 40 emits the counter waves which are aligned with theharmful waves and have the phase angles opposite to those of the harmfulwaves, thereby matching and countering such harmful waves in the targetspace. When desirable, the counter unit 40 may also be disposed at apreset radial or axial distance from the voice coil 22V, where thewavefronts of the counter waves by the counter unit 40 may match thoseof the harmful waves from the voice coil 22V as described in the wavematching. In all of these examples, the speak 22 is converted into theEMC speaker system of this invention by including such a counter unit 40therein. Further configurational and/or operational characteristics ofsuch a counter unit 40 of FIG. 3D are similar or identical to those ofthe counter units of FIGS. 3A to 3C.

The above counter unit 40 may be modified into other configurations, maybe implemented into other dispositions, and/or may counter the harmfulwaves in other mechanisms. For example, such a counter unit may beformed as a solid sheet of other shapes without any openings, a poroussheet of other shapes, and the like. More particularly, the counter unitmay further be contoured to be concave upward (or downward) for bettermatching the wavefronts of such counter waves with those of the harmfulwaves. In another example, the counter unit may be disposed at adifferent distance from the base unit, may be disposed over a differentportion of the voice coil, and the like. In another example, multiplesimilarly or differently shaped counter units may also be disposed invarious arrangements for such local or global countering.

In another example of FIG. 3E, a piezoelectric speaker 22 includes apiezoelectric plate 22P, a pair of electrodes 22E, and a metal plate22M, where each of the electrodes 22E is fixedly coupled to each ofopposite sides of the piezoelectric plate 22P (to be referred to as a“piezo plate” hereinafter), while the metal plate is fixedly attached toone of such electrodes 22E. As well known in the art, the piezo plate22P is arranged to vibrate when alternating source voltage is appliedthereacross by such electrodes 22E, where the metal plate 22Mmechanically supports the piezo plate 22P and electrodes 22E but isgenerally arranged not to vibrate with the piezo plate 22P, where anassembly of the piezo plate 22P and electrodes 22E are frequentlyreferred to as a “piezoelectric element.” Accordingly, the piezoelectricspeaker 22 generates audible sounds in response to the source voltagewhile irradiating the harmful waves by its base units 22P, 22E in thepiezoelectric element. The metal plate 22M may be included in the baseunit as well depending on whether or not the metal plate 22M may affectpaths of the harmful waves therealong. In order to counter the harmfulwaves irradiated from such base units, at least one counter unit 40 ispreferably disposed in a preset relation to various base units 22P, 22Eof the piezoelectric speaker 22. In this example, the counter unit 40 isprovided as a 3-D replica of the base units 22P, 22E which similarlyincludes a piezo plate, two electrodes attached to the sides of thepiezo plate, and a metal plate. In this context, this counter unit 40 isto preferentially operate on the source matching or, more specifically,the shape matching. In order to prevent such a counter unit 40 fromgenerating any audible sounds, however, the piezo plate of this counterunit 40 may be fixedly coupled to a metal plate thereof or otherwisearranged to not vibrate in response to source voltage or an analogthereof supplied thereto. In addition, the counter unit 40 is disposedbelow the piezoelectric speaker 22 in the rear arrangement such that thecounter unit 40 preferably emits the counter waves of amplitudes greaterthan those of such harmful waves due to a greater distance to the targetspace than the base units 22P, 22E. The counter unit 40 is aligned witha longitudinal axis of the speaker 22 so that centers of the wavefrontsof the counter waves coincide with those of the wavefronts of theharmful waves. To ensure such counter waves to define the phase anglesat least partially opposite to those of the harmful waves, the sourcecurrent or its analog may be supplied to the counter unit 40 in adirection opposite to that of the source current flowing in the speaker22. Therefore, the counter unit 40 may emit the counter waves which arealigned with the harmful waves and which define the phase anglesopposite to those of such harmful waves, thereby matching and counteringthe harmful waves in the target space. As mentioned above, the counterunit 40 may be viewed as a 3-D analog of the piezoelectric speaker 22defining the similar shape but a configuration larger or thicker thanthat of the speaker 22. When desirable, the counter unit 40 may bedisposed at a preset distance from the speaker 22 in which thewavefronts of the counter waves from the counter unit 40 may match thoseof the harmful waves from the speaker 22 as have been mentioned in thewave matching. In all of the examples, the speaker 22 is converted intothe EMC speaker system of this invention by including the counter unit40 therein.

The above counter unit 40 may be modified into other configurations, maybe implemented into other dispositions, and/or may counter the harmfulwaves in other mechanisms. For example, such a counter unit may have adifferent radius and/or height while maintaining an aspect ratio of thespeaker or varying such a ratio. In another example, such a counter unitmay have a shape defining the similar aspect ratio but include theplates and electrodes of thicknesses which are different from those ofthe speaker. In another example, the counter unit may also be disposedin the front arrangement in which an upper article of the figure may beviewed as the counter unit and a lower article may be interpreted as thespeaker. In another example, two or more similarly or differently shapedcounter units may be disposed in various arrangements for the local orglobal countering. It is appreciated that the counter unit may have theshape similar to that of the piezoelectric speaker but may be made ofand/or include different materials. For example, the counter unit mayhave a plate made of and/or including insulative or semiconductivematerials which are not piezoelectric but define an electric resistivitysimilar to that of the piezo plate of the speaker. In another example,the electrodes and/or metal plate may be made of and/or includematerials different from those of the speaker but cheaper. As far as thecounter unit may emit the counter waves capable of countering theharmful waves in the target space, the counter unit may define variousconfigurations and may be made of and/or include various materials.

It is also appreciated that the counter unit itself may also operate asan additional piezoelectric speaker which is supplied with the sourcevoltage and generate the audible sounds identical to those produced bythe speaker. However, the counter unit speaker is arranged to emit thecounter waves having the phase angles at least partially opposite tothose of the harmful waves, thereby countering the harmful waves by thecounter waves while generating the same audible sounds as the speaker.Such a counter unit may be embodied in various arrangements. Forexample, the speaker and counter unit may be axially or angularlyaligned with each other, while the source voltage is supplied thereto inopposite directions. In another example, the source voltage may besupplied to both the speaker and counter unit in the same direction, butthe counter unit is configured and/or oriented in such a manner that thecounter waves define the phase angles which are opposite to those of theharmful waves. As long as the piezo plate of the counter unit vibratesin the same direction as that of the speaker and as long as the counterunit as a whole emits the counter waves matching and countering theharmful waves, the counter unit may define various configurations, maybe disposed in various orientations or alignments, and/or may besupplied with the source voltage along various directions.

In another example of FIG. 3F, a piezoelectric speaker 22 similarlyincludes a piezoelectric plate 22P, a pair of electrodes 22E, and ametal plate 22M as that of FIG. 3E. In order to counter the harmfulwaves irradiated from such base units, at least one counter unit 40 ispreferably disposed in a preset relation to the base units 22P, 22E ofthe speaker 22. In this example, the counter unit 40 is formed as a coilof conductive wire similar to that of FIG. 3B. In this context, such acounter unit 40 is to operate on the wave matching. The counter unit 40is disposed below the piezoelectric speaker 22 in the rear arrangementso that the counter unit 40 emits the counter waves of amplitudesgreater than those of the harmful waves due to a greater distance to thetarget space than the base units 22P, 22E. Such a counter unit 40 isaligned with a longitudinal axis of the speaker 22 so that centers ofthe wavefronts of the counter waves coincide with those of thewavefronts of the harmful waves. To ensure such counter waves to havethe phase angles at least partially opposite to those of the harmfulwaves, the source current or its analog may be supplied to the counterunit 40 in a direction opposite to that of the source current flowing inthe speaker 22. Therefore, the counter unit 40 may emit the counterwaves aligned with the harmful waves and having the phase anglesopposite to those of the harmful waves, thereby matching and counteringthe harmful waves in the target space. When desirable, the counter unit40 is disposed at a preset distance from the speaker 22 in which thewavefronts of such counter waves by the counter unit 40 may match thoseof the harmful waves by the speaker 22 as have been mentioned in thewave matching. In all of the examples, the piezoelectric speaker 22 isconverted into the EMC speaker system of the present invention byincorporating the counter unit 40 therein. Further configurationaland/or operational characteristics of the counter unit 40 shown in FIG.3F are similar or identical to those of the counter units of FIG. 3E.

The above counter unit 40 may be modified into other configurations, maybe implemented into other dispositions, and/or may counter the harmfulwaves in other mechanisms. For example, such a counter unit may bedisposed in a different distance from the base units or may enclose oneor more of the base units therein. In another example, the counter unitmay define a radius of curvature which may be smaller than that of thespeaker. In another example, such a counter unit may have the radiuswhich may be constant or may change along its longitudinal axis. Inanother example, multiple similar or different counter units may bedisposed in various arrangements for the local or global countering.

In another example of FIG. 3G, a speaker 22 similarly includes apiezoelectric plate 22P, a pair of electrodes 22E, and a metal plate 22Mas that described in FIG. 3E. In order to counter the harmful wavesirradiated from such base units, at least one counter unit 40 ispreferably disposed in a preset relation to the base units 22P, 22E ofthe speaker 22. In this example, the counter unit 40 is formed as a meshof conductive wire similar to that of FIG. 3C. In this context, thecounter unit 40 is to operate on the wave matching. The counter unit 40is disposed below the piezoelectric speaker 22 in the rear arrangementso that the counter unit 40 emits the counter waves of amplitudesgreater than those of the harmful waves due to a greater distance to thetarget space than the base units 22P, 22E. Such a counter unit 40 isaligned with a longitudinal axis of the speaker 22 so that centers ofthe wavefronts of the counter waves coincide with those of thewavefronts of the harmful waves. To ensure such counter waves to havethe phase angles at least partially opposite to those of the harmfulwaves, the source current or its analog may be supplied to the counterunit 40 in a direction opposite to that of the source current flowing inthe speaker 22. Therefore, the counter unit 40 may emit the counterwaves aligned with the harmful waves and having the phase anglesopposite to those of the harmful waves, thereby matching and counteringthe harmful waves in the target space. When desirable, the counter unit40 is disposed at a preset distance from the speaker 22 in which thewavefronts of such counter waves by the counter unit 40 may match thoseof the harmful waves by the speaker 22 as have been mentioned in thewave matching. In all examples, such a piezoelectric speaker 22 isconverted to the EMC speaker of the present invention by the counterunit 40. Other configurational and/or operational characteristics of thecounter unit 40 of FIG. 3G are similar or identical to those of thecounter units of FIGS. 3E and 3F.

The above counter unit 40 may be modified into other configurations, maybe implemented into other dispositions, and/or may counter the harmfulwaves in other mechanisms. For example, such a counter unit may beformed as a solid annular tube of other shapes without any openings, anannular porous tube of other shapes, and the like. In another example,the counter unit may define a different radius of curvature which may besmaller than those of the base units and may be disposed therein, whichmay be constant or may vary along its longitudinal axis, and the like.In another example, such a counter unit may be disposed to enclosetherein at least a portion or entire portion of the base units whilehaving a radius of curvature which is greater than, similar to or lessthan that of the base units. In another example, multiple similarly ordifferently shaped counter units may be disposed in various arrangementsfor such local or global countering.

In another example of FIG. 3H, a speaker 22 similarly includes apiezoelectric plate 22P, a pair of electrodes 22E, and a metal plate 22Mas that described in FIG. 3E. In order to counter the harmful wavesirradiated from such base units, at least one counter unit 40 ispreferably disposed in a preset relation to the base units 22P, 22E ofthe speaker 22. In this example, the counter unit 40 is formed as a 3-Danalog of the base units 22P, 22E, where such an analog corresponds toan approximation of the base units 22P, 22E, and consists of a presetnumber of concentric rings of wire interconnected by another presetnumber of arcuate wires. In this context, such a counter unit 40 is topreferentially operate on the source matching. The counter unit 40 isdisposed above the piezoelectric speaker 22 in the front arrangement sothat the counter unit 40 emits the counter waves of amplitudes less thanthose of the harmful waves due to a shorter distance to the targetspace. Such a counter unit 40 is aligned with a longitudinal axis of thespeaker 22 such that centers of the wavefronts of the counter wavescoincide with those of the wavefronts of the harmful waves. To ensuresuch counter waves to have the phase angles at least partially oppositeto those of the harmful waves, the source current or its analog may besupplied to such a counter unit 40 along a direction opposite to that ofthe source current flowing through the speaker 22. Accordingly, thecounter unit 40 may emit the counter waves aligned with the harmfulwaves and having the phase angles opposite to those of the harmfulwaves, thereby matching and countering the harmful waves in the targetspace. In this respect, this counter unit 40 similar to that of FIG. 3D,except that this counter unit 40 defines a contour which is concavedownward. When desirable, the counter unit 40 is disposed at a presetdistance from the speaker 22 where the wavefronts of such counter wavesby the counter unit 40 may match those of the harmful waves by thespeaker 22 as have been mentioned in the wave matching. In all of theexamples, such a piezoelectric speaker 22 is converted into the EMCspeaker of this invention by the counter unit 40. Other configurationaland/or operational characteristics of the counter unit 40 of FIG. 3H aresimilar or identical to those of the counter units of FIGS. 3E to 3G.

The above counter unit 40 may be modified into other configurations, maybe implemented into other dispositions, and/or may counter the harmfulwaves in other mechanisms. For example, such a counter unit may beformed as a solid concave sheet of other shapes without any openings, aporous sheet of other shapes, and the like, in which the counter unitmay include different number of rings or arcs and define the openings ofdifferent shapes. In another example, the counter unit may consists ofmultiple sections each of which may be supplied with the electricvoltages of different amplitudes and/or directions for betterapproximating the base units. Such sections may be formed concentricallyso that different voltages may be applied in a radial direction or,alternatively, may be formed angularly so that different voltages may beapplied in an angular direction. In another example, multiple similarlyor differently shaped counter units may be disposed in variousarrangements for such local or global countering.

In another example of FIG. 3I, a speaker 22 similarly includes apiezoelectric plate 22P, a pair of electrodes 22E, and a metal plate 22Mas that described in FIG. 3E. In order to counter such harmful wavesirradiated from such base units, at least one counter unit 40 ispreferably disposed in a preset relation to the base units 22P, 22E ofthe speaker 22. In this example, the counter unit 40 is formed as anannular tube. In this context, the counter unit 40 is to operate on thesource matching. The counter unit 40 is disposed around thepiezoelectric speaker 22 in the flush or concentric arrangement so thatthe counter unit 40 emits the counter waves defining amplitudes similarto those of the harmful waves due to a distance to the target spacesimilar to that from the base units 22P, 22E. The counter unit 40 isaligned with a longitudinal axis of the speaker 22 so that centers ofthe wavefronts of the counter waves coincide with those of thewavefronts of the harmful waves. To ensure such counter waves to havethe phase angles at least partially opposite to those of the harmfulwaves, the source current or its analog may be supplied to the counterunit 40 in a direction opposite to that of the source current flowing inthe speaker 22. Accordingly, the counter unit 40 may emit the counterwaves aligned with the harmful waves and defining the phase anglesopposite to those of such harmful waves, thereby matching and counteringthe harmful waves in the target space. When desirable, the counter unit40 is disposed at a preset distance from the speaker 22 in which thewavefronts of such counter waves by the counter unit 40 match those ofthe harmful waves by the speaker 22 as have been mentioned in the wavematching. In all examples, the piezoelectric speaker 22 is converted tothe EMC speaker of this invention by the counter unit 40. Otherconfigurational and/or operational characteristics of the counter unit40 of FIG. 3G are similar or identical to those of the counter units ofFIGS. 3E and 3F.

The above counter unit 40 may be modified into other configurations, maybe implemented into other dispositions, and/or may counter the harmfulwaves in other mechanisms. For example, such a counter unit may beformed as a porous annular tube of other shapes, an annular solid tubeof other shapes, and the like. In another example, the counter unit maydefine a different radius of curvature which may be smaller than that ofthe base units and disposed therein, which may be constant or may varyalong its longitudinal axis, and the like. In another example, such acounter unit may be disposed to enclose therein a different portion ofthe base units while having a radius of curvature greater than, similarto or less than that of the base units. In another example, multiplesimilarly or differently shaped counter units may be disposed in variousarrangements for the local or global countering. In all of the examples,the speaker 22 is converted into the EMC speaker of this invention bythe counter unit 40. Other configurational and/or operationalcharacteristics of the counter unit 40 of FIG. 3I are similar oridentical to those of the counter units of FIGS. 3E and 3G.

The above counter units exemplified in FIGS. 3A to 3I as well as thosedescribed hereinabove may be disposed in any of the above arrangementsand may counter the harmful waves by any of the foregoing mechanisms.Accordingly, the counter unit which may be shaped similar or identicalto one or more of the base units of various speakers may be disposedlateral or side by side to one or more base units, may be axially,radially, and/or angularly aligned with one or more base units, mayenclose therein one or more base units, may be enclosed by one or morebase units, may wind around one or more base units, may be wound by oneor more base units, and so on, when such a counter unit is to operatebased on the source matching. Alternatively, the counter unit which maybe shaped similar to or different from one or more of the base units maybe disposed along one or more wavefronts of the harmful waves irradiatedby one or more base units for the wave matching. In addition, suchcounter units may be employed in a proper number and/or arrangement tocounter such harmful waves based on the local countering or globalcountering.

As described hereinabove, further details of various EMC speakers andvarious counter units of such EMC speakers have already been provided invarious co-pending Applications one of which is entitled“Electromagnetically-Shielded Actuator Systems and Methods” and carryinga U.S. Ser. No. 11/440,135 and another of which is entitled“Electromagnetically-Countered Speaker Systems and Methods” and carryinga Ser. No. 12/318,538, now issued as U.S. Pat. No. 8,041,048.Accordingly, various conventional devices with such EMC speakers can beconverted into the EMC systems capable of performing their intendedfunctions while countering such harmful waves irradiated by their motorsby such counter units.

In another exemplary embodiment of this aspect of the invention, thecounter units may also be incorporated into various microphones whichare inverse examples of such speakers and which also have various baseunits which are similar to those of the speakers, where examples of thebase units may include, but not be limited to, electromagnets, permanentmagnets, any parts of such microphones through which the unsteadycurrent flows, and any of such parts across which the unsteady voltageis applied. Therefore, any prior art devices which include such EMCmicrophones such as standalone microphones, wired phones, mobile phones,audio devices, audiovisual devices, and assemblies of an earphone andmicrophone may be converted into various EMC systems such as, e.g., EMCstandalone microphones, EMC wired or mobile phones, EMC audio systems,EMC audiovisual systems, and such EMC assemblies, where various counterunits of any of the above configurations may be incorporated thereintoin any of the above dispositions and/or arrangements and may counter theharmful waves in any of the above mechanisms.

In another exemplary embodiment of this aspect of the invention, thecounter units may also be incorporated into various motors to countersuch harmful waves irradiated by their base units, where such motorsfunction to convert the electric energy into mechanical energy orelectromotive force and where examples of the motors may also include,but not be limited to. DC motors, universal motors. AC synchronousmotors. AC induction motors, linear or step motors, and the like.Therefore, any prior art devices (or actuators) including these EMCmotors such as kitchen appliances (e.g., food processors, mixers,juicers, grinders, blenders, squeezers, dish washers, refrigerators,freezers, ice makers, can openers, food dryers, coolers, food steamers,garbage compactors, garbage disposals, and the like), cooking appliances(e.g., electric grills, electric ovens, electric stoves, electricranges, electric toast ovens, electric toasters, their electric fans,coffee makers, espresso makers, heating bottles, and the like),household appliances (e.g., cloth washers, cloth dryers, airconditioners, garage openers, dry or wet vacuum cleaners, and the like),tools (e.g., electric drills, electric saws, electric grinders, electricscrewdrivers, electric nail guns, electric staple guns, electricsanders, electric grinders, and the like), and/or personal hygienedevices (e.g., electric toothbrushes, electric razors, electric hairdryers, and the like) may all be converted into various EMC systems suchas EMC kitchen appliances. EMC cooking appliances. EMC householdappliances. EMC tools, EMC hygiene systems, and the like. In general,the DC motor includes at least one stator with at least one permanentmagnet and at least one rotor with at least one electromagnet, theuniversal motor has at least one stator with at least one electromagnetand at least one rotor with at least one electromagnet, the synchronousAC motor includes therein at least one stator with at least oneelectromagnet and a rotor having at least one permanent magnet, aninduction AC motor includes at least one stator with at least oneelectromagnet and at least one rotor with at least one electricconductor, a linear motor includes therein at least one stator with atleast one electromagnet and at least one rotor with at least onepermanent magnet, and the like. Therefore, the base units of the motorsmay include the rotors, stators, permanent magnets, any parts of themotors in which the unsteady current flows, any of such parts acrosswhich the unsteady voltage applies, and the like. FIGS. 4A to 4F showschematic perspective views of exemplary counter units which areimplemented into motors with various base units according to the presentinvention, where FIGS. 4A to 4C exemplify various counter unitsimplemented into prior art rotors of such motors, whereas FIGS. 4D to 4Fdescribe various counter units implemented into various conventionalstators of the motors. It is appreciated that detailed configurations ofthe stators are omitted in FIGS. 4A to 4C, while only stators areincluded and the matching rotors are omitted in FIGS. 4D to 4F both forsimplicity of illustration. It is, accordingly, appreciated that otherconductive, semiconductive, and/or insulative parts of the motors whichmay emit the harmful waves are to be omitted in all of these figures andthat, when necessary, such parts may be properly countered by resortingto any of such counter units as described above. It is also appreciatedin FIGS. 4A to 4F that various motors and their counter units aredisposed so as to define the target spaces therearound, in the front ofsuch motors (i.e., top of the figures) or in the rear thereof (i.e.,bottom of the figures). It is further appreciated that details ofvarious counter units of this embodiment have been disclosed in theco-pending Application of U.S. Ser. No. 12/318,539 entitled“Electromagnetically-Countered Actuator Systems and Methods,” now issuedas U.S. Pat. No. 8,148,872.

In one example of FIG. 4A, a motor 24 includes a rotor unit 25 and astator unit 26, where such a rotor unit 25 is rotatably disposed insideor enclosed by the stator unit 26. The rotor unit 25 includes a singleinner base rotor 25N of an electromagnet, while the stator unit 26includes a single inner base stator 26N of a permanent magnet. As wellknown in the art, such a base rotor 25N defines dynamic magnetic fieldsas the source current flows therein, and an interaction between thedynamic magnetic fields of the base rotor 25 and static magnetic fieldsof the base stator 26N rotates the rotor unit 25 in a clockwise orcounterclockwise direction, while reversing the direction of the sourcecurrent to the base rotor 25N to maintain rotation of the rotor unit 25in every 180°. During its rotation, the rotor unit 25 irradiates theharmful waves as the source current flows therein, while the stator unit26 receives and then transmits such harmful waves therethrough whileaffecting propagation paths of the harmful waves depending uponpolarities of the harmful waves. In this context, both the rotor andstator units 25, 26 or, more specifically, the base rotor and stator25N, 26N serve as the base units for this motor 24. In order to counterthe harmful waves irradiated by the base units 25N, 26N, at least onecounter unit 40 is preferably disposed in a preset relation to such baseunits 25N, 26N of the motor 25. In this example, the counter unit 40includes a pair of outer counter rotors 25U and an optional outer stator26U, where each of the counter rotors 25U is shaped as anotherelectromagnet similar to that of the base rotor 25N and where thecounter stator 26U is shaped as another permanent magnet similar to thatof the base stator 26N. In this context, the counter rotors 25U operateon the source matching. More specifically, the counter rotors 25U aredisposed laterally to the base rotor 25N and oriented to abut the samemagnetic poles of the base rotor 25N. In addition, the counter units 25Umechanically couple with the base rotor 25N such that the above lateralarrangement and abutting orientation may be maintained during therotation of the rotor unit 25. Therefore, the counter rotors 25U mayemit such counter waves which are aligned with the harmful waves andwhich define the phase angles at least partially opposite to those ofthe harmful waves, thereby matching and countering the harmful waves inthe target space. Similar to the counter rotors 25U, the counter stator26U is disposed in the lateral and concentric arrangements to the basestator 26N and abuts the same magnetic poles of the base stator 26N.Accordingly, the counter stator 25N may emit such counter waves whichare aligned with the harmful waves and which also defines the phaseangles at least partially opposite to those of the harmful waves,thereby matching and countering such harmful waves in the target space.Because both of the counter rotors 25U and stator 26U counter theharmful waves irradiated by the base rotor 25N and stator 26N, this EMCmotor 24 effectively minimizes irradiation of the harmful waves from thebase units 25N, 26N thereof.

In another example of FIG. 4B, a motor 24 similarly includes a rotorunit 25 and a stator unit 26, where the rotor unit 25 is rotatablydisposed inside or enclosed by the stator unit 26. The stator unit 26includes two outer base stators 26U which are permanent magnets orelectromagnets, disposed on opposite sides of the rotor unit 25, andarranged to define the same magnetic polarity. This rotor unit 25includes a pair of inner rotors 25N of electromagnets which define thesame shape and size, which are disposed symmetrically with respect to arotation axis of the rotor unit 25, and which abut each other by thesame magnetic poles. In this context, the rotor unit 25 is to operatepreferentially on the source matching. These inner rotors 25N may beinterpreted in various ways. For example, one of the inner rotors 25Nmay be deemed to serve as a base rotor, while the other of such isarranged to function as a counter rotor. Therefore, one of the rotors25N irradiates the harmful waves, while the other thereof emits thecounter waves aligned with the harmful waves, having the phase angles atleast partially opposite to those of the harmful waves and, therefore,countering the harmful waves in the target space. In another example,both of such inner rotors 25N may be regarded as the base (or counter)rotors which irradiate the harmful waves but are also arranged tocooperate each other through canceling such harmful waves and/orsuppressing the harmful waves irradiated by the other from propagatingoutwardly. The stator unit 26, which encloses such inner rotors 25Nreceives and transmits the harmful waves therethrough while affectingpropagation paths of such harmful waves depending upon polarities of theharmful waves. When desirable, additional stator units may also beincorporated between the inner rotors 25N and/or around the outer stator26U in order to counter the harmful waves transmitting through the outerstator 26U. Further configurational and/or operational characteristicsof the motor 24 of FIG. 4B are similar or identical to those of themotor of FIG. 4A.

In another example of FIG. 4C, a motor 24 similarly includes a rotorunit 25 and a stator unit 26, where the rotor unit 25 is rotatablydisposed inside the stator unit 26 or is enclosed thereby. Each of therotor and stator units 25, 26 are similar to those of FIG. 4A, so thatan inner rotor 25N serves as a base rotor, that a pair of outer rotors25U function as counter rotors, that a pair of inner stators 26N serveas base stators, and that an optional pair of outer stators 26U functionas counter stators. It is appreciated, however, that each inner stator26N defines a pair of opposite poles while abutting the adjacent pole ofthe inner rotor 25N by an opposite pole. Accordingly, the outer rotor25U is abutted by another pole of the inner stator 26N which is alsoopposite to the adjacent pole of the outer rotor 25U. Such anarrangement may be more effective for countering the harmful waves butmay instead decrease an efficiency in generating the electromotiveforce. Other configurational and/or operational characteristics of themotor 24 of FIG. 4C may be similar or identical to those of the motorsof FIGS. 4A and 4B.

In another example of FIG. 4D, a motor 24 includes a rotor unit (notincluded in this figure) and a stator unit 26, where the stator unit 26includes two sets of stators 26N, 26U and where any of the above rotorunits and other rotor units disclosed in the above co-pendingApplication may be used in conjunction with the stator unit 26. Morespecifically, a first set of the stator unit 26 includes a pair ofC-shaped inner stators 26N, while a second set of the stator unit 26includes another pair of larger C-shaped outer stators 26U. In addition,each pair (i.e., a right pair and a left pair) of the inner and outerstators 26N, 26U are arranged to physically abut each other and alsomagnetically abut each other by their poles of opposite polarities.Accordingly, one of such stators 26N, 26U may counter the harmful wavestransmitting through the other. In this embodiment, various rotor unitsmay be disposed inside such inner stators 26N, between the inner andouter stators 26N, 26U, outside the outer stators 26U, and the like.Accordingly, whether a specific stator serves as a basic stator or acounter stator may depend on the disposition of the basic and/or counterrotors. Other configurational and/or operational characteristics of themotor 24 of FIG. 4D may be similar or identical to those of the motorsof FIG. 4A through 4C.

In another example of FIG. 4E, another motor 24 has a rotor unit (notincluded in this figure) and a stator unit 26, where the stator unit 26includes two sets of stators 26N, 26U and where any of the above rotorunits and other rotor units disclosed in the above co-pendingApplication may be used in conjunction with the stator unit 26. Morespecifically, a first set of the stator unit 26 includes therein fouridentical inner stators 26N angularly disposed around an axis ofrotation of the rotor unit, while a second set of the stator unit 26includes a pair of larger C-shaped outer stators 26U. Similar to that ofFIG. 4D, the stator unit 26 of this embodiment may include various rotorunits inside such inner stators 26N, between the inner and outer stators26N, 26U, and/or outside the outer stators 26U. Therefore, whether aspecific stator serves as a basic stator or a counter stator may dependon the disposition of such basic and/or counter rotors. Furtherconfigurational and/or operational characteristics of the motor 24 ofFIG. 4E are similar or identical to those of the motors of FIGS. 4A to4D.

In another example of FIG. 4F, another motor 24 has a rotor unit (notincluded in the figure) and a stator unit 26, where the stator unit 26includes a pair of C-shaped stators 26L, 26R of the same or similarsizes. More specifically, each of the left stator 26L and right stator26R spans about or beyond 270°. In addition, such stators 26L, 26R aredisposed in the concentric arrangement while misaligning their gaps suchthat the stators 26L, 26R overlap each other along most side portions ofthe stator unit 26. Other configurational and/or operationalcharacteristics of the motor 24 of FIG. 4F may be similar or identicalto those of the motors of FIGS. 4A to 4E.

As described hereinabove, further details of such rotor and stator unitsof various EMC motors and various counter units for the EMC motors havebeen provided in the co-pending Application which is entitled“Electromagnetically-Countered Actuator Systems and Methods” and whichhas the U.S. Ser. No. 12/318,539 now issued as U.S. Pat. No. 8,148,872.Therefore, various prior art devices including such EMC motors can beconverted into the EMC systems capable of performing their intendedfunctions while countering such harmful waves irradiated by their motorsby such counter units.

In another exemplary embodiment of this aspect of the invention, thecounter units may also be incorporated into various electric generatorswhich are inverse examples of such motors and which include various baseunits which are similar to those of the motors, where examples of thebase units may include, but not be limited to, electromagnets, permanentmagnets, any parts of the generators in which the unsteady currentflows, any parts of the generators across which the unsteady voltage isapplied, and the like. Therefore, any conventional devices which includethe EMC generators such as AC generators, DC generators, and(automobile) alternators may be converted into the EMC systems such asEMC AC generators, EMC DC generators, EMC alternators, and so on, wherevarious counter units of any of such configurations may be incorporatedthereinto in any of such dispositions and/or arrangements, and maycounter the harmful waves in any of the above mechanisms.

In another exemplary embodiment of this aspect of the invention, thecounter units may also be incorporated into various heating units forcountering the harmful waves irradiated by their base units, where suchheating units function to convert electric energy into heat (or thermalenergy) and then to transfer the heat to an user by thermal conduction,convection, and/or radiation and where examples of such heating unitsmay include, but not be limited to, resistive wires, resistive strips,resistive coils, resistive solenoids, resistive toroids, resistivesheets, and the like. Accordingly, any prior art heating devicesincluding such heating units such as personal heating appliances (e.g.,electric mattresses. electric mats, electric blankets, electric heatingpads, and the like), cooking appliances (e.g., electric grills, electricovens, electric stoves or ranges, electric toast ovens, electrictoasters, coffee makers, espresso makers, heating bottles, and thelike), beauty appliances (e.g., hair dryers, hair setters, hair curlers,hair steamers, and the like), may be converted into such EMC personalheating systems, EMC cooking systems, EMC beauty systems, and the like.In general, such heating units include the above resistive parts as wellas other parts for supporting or retaining the resistive parts in fixedor variable positions, for insulating other articles, and the like.Therefore, the base units of the heating units may include suchresistive parts, any parts of the heating units in which the unsteadycurrent flows, any of such parts across which the unsteady voltageapplies, any of such parts capable of affecting the propagation paths ofthe harmful waves irradiated from other parts of the heating units, andthe like. FIGS. 5A to 5H show schematic perspective views of exemplarycounter units which are implemented into heating units having variousbase units according to the present invention, where FIGS. 5A to 5Cexemplify various counter units implemented into conventional wire-,strip- or sheet-type heating units, respectively, while FIGS. 5D to 5Hdepict various counter units implemented into various conventionalcoil-type heating units. It is appreciated in these figures that variousheating units only include various resistive articles and counter unitstherefor and that other parts of the heating units are omitted thereinfor simplicity of illustration. Therefore, other conductive,semiconductive, and/or insulative parts of the heating units which mayemit the harmful waves are omitted in the figures and that, whennecessary, such parts may be properly countered by resorting to any ofsuch counter units as described above. It is also appreciated in FIGS.5A to 5H that various base units and counter units of such heating unitsare disposed in order to form the target spaces therearound, e.g., inthe front of the heating units (i.e., above the sheet), in the rearthereof (i.e., below the sheet), in the top thereof (i.e., top of thefigure), and the like. It is also appreciated that details of variouscounter units of this embodiment have been disclosed in the co-pendingApplication of U.S. Ser. No. 11/289,693 entitled“Electromagnetically-Shielded Heat Generating Systems and Methods.”

In one example of FIG. 5A, a heating unit 28 includes at least oneresistive article and a counter unit 40, where the resistive article isformed as a resistive wire or resistive rod 28W which is capable ofconverting electric energy into heat when electric current flows thereinwhile irradiating the harmful waves and where the resistive wire or rod28W serves as the base unit of such a heating unit 28. In order tocounter the harmful waves irradiated by the base unit 28W, the counterunit 40 is provided as a coil which is helically wound in a presetdirection to the base unit 28W of the heating unit 28. In this context,the counter unit 40 is to preferentially operate on the wave matching.More specifically, such a counter unit 40 concentrically encloses thebase unit 28W in its center and oriented symmetrically to the base unit28W. In addition, the electric current is supplied to the base andcounter units 28W, 40 in opposite directions. Therefore, the counterunit 40 emits such counter waves which are aligned with the harmfulwaves and also define the phase angles at least partially opposite tothose of the harmful waves, thereby countering the harmful waves in thetarget space by matching the wavefronts of the harmful waves with thoseof the counter waves. Although seemingly similar to a conventionalcoaxial wire, the heating unit 28 of the example differs therefrom in afew major aspects. First of all, contrary to the coaxial wire in whichmultiple conductive elements are concentrically disposed, the heatingunit 28 includes the resistive wire or rod 28W which defines a finiteelectric resistance and generates the heat when the current flowstherein. Secondly, the heating unit 28 includes the counter unit 40which encloses the base unit 28W in a sparse arrangement or, in otherwords, the counter unit 40 may form multiple openings or gapstherethrough, where characteristic dimensions of the openings or gapsmay be tens or hundreds of times greater than a characteristic dimensionof the base unit 28W. Therefore, such a counter unit 40 may beimplemented at a less cost with a lesser amount of resistive material.It is appreciated in this example that such a counter unit 40 may bemade of and/or include a conductive material or that the counter unit 40itself may also be made of and/or include the resistive material andserve as another resistive article. It is also appreciated that thecounter unit 40 may be wound around the base unit 28 in any direction asfar as the electric current is supplied thereto in a direction oppositeto that of the source current supplied to the resistive wire (or rod)28W. It is to be understood in such an example that the heating unit 40of this example may define the target space all around its length.

In another example of FIG. 5B, a heating unit 28 similarly includes atleast one resistive article and at least one counter unit 40, where theresistive article is shaped as a resistive strip 28 t which is capableof converting electric energy into heat as electric current flowstherein while irradiating such harmful waves and where the counter unit40 is provided as another coil of a conductive or resistive material.Similar to that of FIG. 5A, such a counter unit 40 may be wound alongany direction and form multiple gaps or openings. When desirable, thecoil 40 may also be collapsed to define an oval cross-section andoriented to receive a width or height of the resistive strip 28 t alongits long axis for better approximating the shape of the base unit 28 t.Other configurational and/or operational characteristics of the heatingunit 28 of FIG. 5B are similar or identical to those of the heating unitof FIG. 5A.

In another example of FIG. 5C, a heating unit 28 similarly includes atleast one resistive article and at least one counter unit 40, where theresistive article is defined as a resistive sheet 28H which is capableof converting electric energy into heat as electric current flowstherein while irradiating the harmful waves and where the counter unit40 is formed as another sheet of a conductive or resistive material.More particularly, the counter unit 40 is oriented parallel to the baseunit 28H and disposed at a preset distance therefrom such that thecounter unit 40 operates on the shape matching. Therefore, the counterunit 40 emits such counter waves which is aligned with the harmful wavesand define the phase angles at least partially opposite to those of theharmful waves, thereby capable of countering the harmful waves by thecounter waves in the target space. It is appreciated that amplitudes ofthe electric current supplied to the counter unit 40 may be decided byon which side of the base unit 28H the target space is to be defined.When the target space is formed on the front of the heating unit 28 (orover the sheet), the counter unit 40 is to emit the counter waves withthe amplitudes greater than those of the harmful waves, therebycountering such harmful waves at a greater distance than from the baseunit 28H. When the target space is defined on the rear of the heatingunit 28 (or below the sheet), the counter unit 40 is to emit the counterwaves defining the amplitudes less than those of the harmful waves,thereby countering such harmful waves at a shorter distance than thebase unit 28H. When the target space is defined on top of the heatingunit 28, the counter unit 40 emits the counter waves with the amplitudessimilar to those of the harmful waves, thereby countering such waves ata similar distance as such a base unit 28H. Other configurational and/oroperational characteristics of the heating unit 28 of FIG. 5C aresimilar or identical to those of the heating units of FIGS. 5A and 5B.

In another example of FIG. 5D, a heating unit 28 similarly includes atleast one resistive article and at least one counter unit 40, where theresistive article is formed as a resistive coil 28C capable ofconverting electric energy into heat when electric current flows thereinwhile irradiating the harmful waves and where the resistive coil 28Cserves as the base unit of such a heating unit 28. In order to counterthe harmful waves irradiated by the base unit 28C, the counter unit 40is provided as a rod or a wire which is disposed inside the heating coil28C and aligned with a center of the coil 28C. In this context, thecounter unit 40 is to preferentially operate on the wave matching. Morespecifically, such a counter unit 40 is enclosed by the base unit 28W inits center and oriented symmetrically to the base unit 28W. In addition,the electric current is supplied to the base and counter units 28W, 40in opposite directions. Therefore, the counter unit 40 emits the counterwaves which are aligned with the harmful waves and define the phaseangles at least partially opposite to those of the harmful waves,thereby countering the harmful waves in the target space by matching thewavefronts of such harmful waves by those of the counter waves. Althoughseemingly similar to a conventional coaxial wire, the heating unit 28 ofthe example similarly differs therefrom in a few major aspects asdescribed in FIG. 5A. It is appreciated in this example that the counterunit 40 may also be made of and/or include a conductive material or thatthe counter unit 40 itself may also be made of and/or include theresistive material and serve as another resistive article. It is alsoappreciated that the counter unit 40 may be wound around the base unit28 in any direction as far as the electric current is supplied theretoin a direction opposite to that of the source current supplied to theresistive coil 28C. It is appreciated in this example that the heatingunit 40 of this example may define the target space all around itslength. Other configurational and/or operational characteristics of theheating unit 28 of this example are similar or identical to those of theheating units of FIGS. 5A to 5C.

In another example of FIG. 5E, a heating unit 28 similarly includes atleast one resistive article and at least one counter unit 40, where theresistive article is defined as a resistive coil 28C which is capable ofconverting electric energy into heat as electric current flows thereinwhile irradiating such harmful waves and where the counter unit 40 isprovided as another coil of a conductive or resistive material so thatthe counter unit 40 preferentially is to operate on the wave matching.In particular, the counter unit 40 is aligned parallel to the base unit28C and also disposed at a preset distance from the base unit 28C.Accordingly, the counter unit 40 emits such counter waves which isaligned with the harmful waves and define the phase angles at leastpartially opposite to those of the harmful waves, thereby capable ofcountering the harmful waves in the target space. It is appreciated thatamplitudes of the electric current supplied to such a counter unit 40may depend on in which side of the base unit 28H the target space isdefined. When the target space is to be formed on the front of theheating unit 28 or over the sheet, the counter unit 40 is to emit thecounter waves with the amplitudes greater than those of the harmfulwaves, thereby countering such harmful waves at a greater distance thanfrom the base unit 28H. When the target space is to be defined on therear of the heating unit 28 (or below the sheet), the counter unit 40 isto emit the counter waves of the amplitudes less than those of suchharmful waves, thereby countering the harmful waves at a shorterdistance than from the base unit 28H. When the target space is to beformed on top of the heating unit 28, the counter unit 40 emits thecounter waves of the amplitudes similar to those of the harmful waves,thereby countering the waves at a similar distance as such a base unit28H. Other configurational and/or operational characteristics of theheating unit 28 of FIG. 5E are similar or identical to those of theheating units of FIGS. 5A to 5D.

Therefore, the counter unit 40preferentially is to operate on the source matching. More particularly,the counter unit 40 is aligned parallel to a center of the base unit 28Cand emit the counter waves which is aligned with the harmful waves anddefine the phase angles at least partially opposite to those of theharmful waves, thereby countering the harmful waves in the target space.It is appreciated that the counter units 40 may be wound in anydirections, e.g., along the same direction as the heating coil 28C as inFIG. 5F or along a direction opposite to that of the heating coil 28C asin FIG. 5G. In either example, the counter unit 40 defines the targetspace at least substantially around the heating unit 28. Otherconfigurational and/or operational characteristics of the heating units28 of FIGS. 5F and 5G are similar or identical to those of the heatingunits of FIGS. 5A to 5E.

In another example of FIG. 5H, a heating unit 28 also includes at leastone resistive article and at least one counter unit 40, where theresistive article is defined as a resistive coil 28C for convertingelectric energy into heat when electric current flows therein whileirradiating such harmful waves and where the counter unit 40 is providedas another coil of a conductive or resistive material intertwined withthe resistive coil 28C. so that the resistive and counter coils 28C, 40alternate each other in every pitch of the heating unit 28 In thiscontext, the counter unit 40 operates on the source matching. Moreparticularly, such a counter unit 40 is aligned parallel to a centerline of the base unit 28C, disposed in a symmetric arrangement withrespect to the resistive coil 28C, and emits the counter waves alignedwith the harmful waves and having the phase angles at least partiallyopposite to those of the harmful waves, thereby countering such harmfulwaves in the target space. It is appreciated that the counter unit 40may be wound in the same direction as the heating coil 28C whiledefining the target space at least substantially around the heating unit28. Other configurational and/or operational characteristics of theheating unit 28 of FIG. 5H are similar or identical to those of theheating units of FIGS. 5A to 5G.
